Double cross: Dr. Jason Cole has many things – a successful career as a neurosurgeon, confident charm, a heart of gold… and a deep dark secret. Every night, at 8.25pm, his alternate personality, Ian Price, emerges for exactly 12 hours. Ian is everything Jason isn't – seductive, devious and a borderline sociopath who's hell bent on taking revenge on Jason for trying to keep him suppressed. With everyone Jason cares about at risk, can he put a stop to Ian's rampage or will they bring each other down in the crossfire?
