Disappeared - Season 4 Episode 2 The Dark Ravine

Mandy Stokes leaves her apartment to run errands on the Sunday after Thanksgiving in 2007. When she doesn’t return by the next morning, friends and family aren’t immediately concerned, but Mandy’s mother feels that something is wrong. Her intuition sparks a missing person’s investigation by Oakland Police that leads from the apartment Mandy shared with her brother to the cavernous ravine where her car is found abandoned. In a bizarre twist, police transfer the case to the Homicide Unit, and her mother’s worst nightmare begins to unfold as she is forced to consider the possibility that her own son is involved in Mandy's disappearance.
