When a mysterious package arrives on the doorstep of Vera Manor, Mel and Kaela must turn to Dev to try and stop the Tallyman's (guest star ) deadliest attack yet. Meanwhile, Maggie is forced to do court-ordered "anger management" with a very unorthodox therapist.

Mel, Maggie and Kaela must divide and conquer when they become aware of a new, formidable threat inspired by the Tallyman. Maggie and Harry team up to chase down a lead in a dangerous magical realm. Mel needs Jordan's help healing a "creature" with whom she has a deep emotional connection. And Kaela's budding flirtation with Dev must contend with a surprise visitor from her past.
