Inclusion Criteria:
* The patient must have signed and dated an Institutional Review Board (IRB)-approved consent form that conforms to federal and institutional guidelines
* Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2
* Diagnosis of adenocarcinoma of the rectum with the major portion of the tumor intact; Note: prior to randomization, the investigator must specify and document each of the following:
* Distance of the lowest tumor margin from the anal verge; and
* Intent for sphincter sparing or non-sphincter sparing surgical resection according to the primary surgeon; and
* The majority of the untreated tumor must be \< 12 cm from the anal verge or below the peritoneal reflection as determined by the treating surgeon
* The tumor must be clinically determined to be locally advanced stage II or stage III rectal cancer, and must also meet any ONE of the following criteria:
* Distal location (as defined by measurement on magnetic resonance imaging \[MRI\], transrectal ultrasound \[ERUS\]/pelvic computed tomography \[CT\] \[with IV contrast\] scan or palpable on digital rectal examination \[DRE\]): cT3-4 =\< 5 cm from the anal verge, any N
* Bulky: any cT4 or evidence that the tumor is adjacent to (defined as within 3 mm of) the mesorectal fascia on MRI or ERUS/pelvic CT (with IV contrast) scan
* High risk for metastatic disease with 4 or more regional lymph nodes (cN2); clinical nodal or "cN" status for eligibility includes the total number of nodes (N2 = 4 or more) in the mesorectal and superior rectal stations measuring \>= 1.0 cm in any axis on cross sectional or endoscopic imaging; Note: nodes must measure 1.0 cm or greater to be considered positive for this eligibility requirement
* Not a candidate for sphincter-sparing surgical resection prior to neoadjuvant therapy (as planned by the primary surgeon)
* Note: clinical stage of the primary tumor and nodes may be determined locally by rectal endoscopic ultrasound or pelvic MRI (pelvic MRI is strongly preferred); CT scan with IV contrast is acceptable provided there is evidence of T4 and/or N2 disease
* Patients must have the ability to swallow and retain oral medication
* Absolute neutrophil count (ANC) must be \>= 1200/mm\^3 (within 28 days before randomization)
* Platelet count must be \>= 100,000/mm\^3 (within 28 days before randomization)
* Hemoglobin must be \>= 10 g/dL (within 28 days before randomization)
* Total bilirubin must be =\< ULN (upper limit of normal) for the lab unless the patient has a bilirubin elevation \> ULN to 1.5 x ULN due to Gilbert's disease or similar syndrome involving slow conjugation of bilirubin (within 28 days before randomization)
* Alkaline phosphatase must be =\< 3 x ULN for the lab (within 28 days before randomization)
* Aspartate aminotransferase (AST) must be =\< 3 x ULN for the lab (within 28 days before randomization);
* Note: if alanine aminotransferase (ALT) is performed instead of AST (per institution's standard practice), the ALT value must be =\< 3 x ULN; if both were performed, the AST must also be =\< 3 x ULN; if AST and/or ALT is \>= ULN but =\< 3 x ULN, serologic testing for hepatitis B and C must be performed and results for viral infection must be negative
* Serum creatinine =\< ULN for the lab and measured or calculated creatinine clearance \> 60 mL/min (within 28 days before randomization)
* Serum potassium, magnesium, and calcium levels within 28 days before randomization must be within normal limits (WNL) for the lab
* International normalized ratio of prothrombin time (INR) within 28 days before randomization must be =\< ULN for the lab; patients who are therapeutically treated with an agent such as warfarin may participate if they are on a stable dose and no underlying abnormality in coagulation parameters exists per medical history
* Patients with acquired immunodeficiency syndrome (AIDS-related illnesses) or known human immunodeficiency virus (HIV) disease must:
* Have a cluster of differentiation (CD)4 count \>= 200 cells/uL within 30 days before beginning study therapy
* Be off all antiretroviral therapy (prophylaxis/treatment) more than 60 days before beginning study therapy, and
* Have no evidence of opportunistic infections
* Pregnancy test (urine or serum beta-human chorionic gonadotropin \[HCG\]) done within 72 hours before randomization must be negative (for women of childbearing potential only); if urine pregnancy results are positive or cannot be confirmed as negative, a serum pregnancy test will be required
Exclusion Criteria:
* Rectal cancer histology other than adenocarcinoma (i.e., sarcoma, lymphoma, squamous cell carcinoma, mucosal melanoma, etc.)
* Definitive clinical or radiologic evidence of metastatic disease; required imaging studies must have been performed within 28 days prior to randomization; Note: Distant clinical staging to exclude patients with overt metastatic disease is determined by:
* Chest: CT scan (preferred); chest x-ray posterioranterior (PA) and lateral (acceptable); or positron emission tomography (PET) scan (acceptable)
* Abdomen: CT scan with IV contrast (preferred); or MRI (acceptable)
* Pelvis: MRI (preferred) or CT scan with IV contrast (acceptable)
* (It is recommended that the same imaging tests that are performed before randomization be used at follow-up time points; Note: CT scans of the abdomen and pelvis must be performed with IV contrast)
* History of prior invasive rectal malignancy, regardless of disease-free interval
* Cardiac disease that would preclude the use of any of the drugs included in the GI002 treatment regimen; this includes but is not limited to:
* Clinically unstable cardiac disease, including unstable atrial fibrillation, symptomatic bradycardia, unstable congestive heart failure, active myocardial ischemia, or indwelling temporary pacemaker
* Ventricular tachycardia or supraventricular tachycardia that requires treatment with class Ia antiarrhythmic drugs (e.g., quinidine, procainamide, disopyramide) or class III antiarrhythmic drug (e.g., sotalol, amiodarone, dofetilide); use of other antiarrhythmic drugs is permitted
* Second- or third-degree atrioventricular (AV) block unless treated with a permanent pacemaker
* Complete left bundle branch block (LBBB)
* History of long QT syndrome
* Corrected QT (QTc) \>= 450 ms

* History of, or any evidence of active, non-infectious pneumonitis
* Active inflammatory bowel disease (i.e., patients requiring current medical interventions or who are symptomatic) or have a history of abdominal surgery or other medical condition that may, in the opinion of the treating physician, interfere with gastrointestinal motility or absorption
* Active autoimmune disease that has required systemic treatment within the past 2 years (i.e., with use of modifying agents, corticosteroids, or immunosuppressive drugs); replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment
* History of active TB (Bacillus tuberculosis)
* Active or chronic infection requiring systemic therapy
* Diagnosis of immunodeficiency or receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of study therapy; the use of physiologic doses of corticosteroids may be approved after consultation with the study principal investigator (PI)
* Active seizure disorder uncontrolled by medication
* Any antineoplastic therapy for this cancer before randomization
* Synchronous colon cancer
* Other invasive cancer within 5 years before randomization; exceptions are colonic polyps, non-melanoma skin cancer or carcinoma-in-situ of the cervix
* Antineoplastic therapy (e.g. chemotherapy or targeted therapy) for other invasive cancer within 5 years before randomization; (for the purposes of this study, hormonal therapy is not considered chemotherapy)
* Prior treatment with an investigational compound being tested in this study (e.g., poly ADP ribose polymerase \[PARP\] inhibitor, anti-PD-1, anti-PD-L1, or anti-PD-L2)
* Receipt of live vaccination within 28 days before randomization; seasonal flu vaccines that do not contain live virus are permitted
