As Cassie struggles to make sense of Lexie’s life and death, we delve into her own difficult past. Meanwhile, Rob's past finally yields some results in the Katy investigation.

While the authorities search for who Lexie was, Frank and Cassie want to discover why she was murdered. Frank wants Cassie to go undercover in Whitethorn House, where Lexie lived with her four best friends. Cassie initially resists, but a disastrous night with Rob sends her running back to Lexie.
