When the radical Islamist group Boko Haram kidnapped nearly 300 Nigerian schoolgirls in April, it sparked international outrage and worldwide pressure to #BringBackOurGirls. But now, FRONTLINE investigates evidence that in the fight against Boko Haram, members of the Nigerian military and state-sponsored militias have been committing atrocities against suspects, many of them innocent civilians.

FRONTLINE travels to the epicenter of the Ebola crisis to find out how and why the outbreak has spiraled out of control — and to track the fight to contain the virus’s deadly spread. With special access to teams fighting Ebola in Sierra Leone, FRONTLINE, in collaboration with the Channel 4 foreign affairs series Unreported World, brings you an up-close, on-the-ground look at how and why the outbreak is endangering civilians and health-care workers, overwhelming hospitals and getting worse.
