“Wanted for multiple crimes, Dr. Albert Beck assumes the identity of another doctor enroute to a new job at a sleep clinic,” the synopsis shares. “He falls for his first patient: Michelle [Emilie Ullerup, ‘Chesapeake Shores’], who suffers from nocturnal sexsomnia - until his interest is derailed by the arrival of her beautiful niece [Angeline Appel, ‘Shameless’] who suffers from a similar condition.”

The synopsis continues: “Beck turns his romantic attentions to the younger woman, causing Michelle to grow suspicious and alerting clinic director, Pamela [Felissa Rose, ‘Family Possessions’], who also begins to question Beck’s erratic behavior.”

With the trailer (watch above) showing Dr. Beck taking advantage of the conditions the women suffer from in order to get close to them, use them sexually and use them to commit crimes, will he finally slip up enough to be stopped? Or will he just quickly pick up and move on to other locations and other victims?
