Stroop: Journey into the Rhino Horn War (2018)

Two first-time filmmakers stop their lives to find out why rhinos are being killed for their horns. Carving out six months for the project, the women quickly find themselves immersed in a world far larger and more dangerous than they had imagined, only emerging from their odyssey four years later.

Unfortunately the movie Stroop: Journey into the Rhino Horn War is not yet available on HBO Max.
