The Other Lamb

Selah, a teenage girl, lives in a remote forest compound with a polygamist cult, where the controlling messianic leader, Shepherd, holds sway. The group is divided into two groups: the younger Sisters, who dress in blue, and the older Wives, who dress in red. As she matures, Selah becomes more of a focus of the Shepherd's attention, and she appears drawn to him. She encounters banished Wife Sarah, who warns her of the Shepherd's violent tendencies, and begins to doubt his judgement. As the group journeys to a new home, Selah's visions of the Shepherd attempting to drown her intensify, and she resists his advances. Eventually, the Wives are found dead, and the Sisters, led by Selah, congregate at the waterfall near their original compound.
