* For females of child-bearing potential, negative serum or urine pregnancy test within 14 days prior to radiation simulation
* The patient or a legally authorized representative must provide study-specific informed consent prior to study entry
* Prior Treatment:
* Patients may or may not have received radiotherapy or neoadjuvant or adjuvant chemotherapy in the treatment of their initial, non-metastatic breast cancer, but must be entered on study after their last dose of radiotherapy, last cycle of chemotherapy and biologic therapy (if applicable) and have sufficient resolution of side effects per physician assessment at time of radiotherapy. Prior immunotherapy for treatment of early stage breast cancer is allowed if metastatic recurrence occurs ≥ 6 months after last dose of immunotherapy
* Patients must have not active wound healing issues from surgery and sufficient resolution of surgical side effects, per physician assessment, at time of radiotherapy
* Patients are not eligible if they have received chemotherapy in the advanced/metastatic setting

* Patients may have received bisphosphonates or rank ligand inhibitors prior to enrollment on study
Exclusion Criteria:
* Prior chemotherapy or targeted therapy for metastatic triple negative breast cancer before start of pembrolizumab plus partner chemotherapy. Prior chemotherapy (including taxanes) administered in the context of curative therapy (if treatment was completed \> 6 months) prior to enrollment into the trial is allowed
* Previous radiation to the metastases to be treated with radiation on this protocol
* Untreated central nervous system (CNS) disease (patients with stable CNS disease for at least 28 days and asymptomatic treated CNS metastases are permitted)

\* Patients who are receiving bisphosphonate therapy specifically to prevent skeletal prevents and who do not have a history of clinically significant hypercalcemia are eligible
* History (Hx) of autoimmune disease that has required systemic treatment (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs).

* HIV positive with CD4 count \< 200 cells/ microliter
* Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy. Indolent cancers (such as low risk prostate or in-situ cancers) that are not being treated, are acceptable
* Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator. Examples include:
* Major surgical procedure within 28 days prior to randomization or anticipation of the need for a major surgical procedure during the course of the study other than for diagnosis
* Known hypersensitivity to nab-paclitaxel or to any of the excipients
* Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
