When Jo Tiegan is given an oval-shaped mirror, as a gift, by the elderly owner of an antique shop, she is amazed to see another girl's image in the mirror instead of her own reflection. It is also quite obvious that the other girl can see her just as clearly. Jo (from the 1990's) and 'the girl in the mirror', Louisa Iredale (from 1919), later accidently find that they can also travel to each other's times through the mirror - following upon which discovery a relentless sequence of events is set in motion.

A dysfunctional gang of criminals takes a middle class Maori family hostage and discovers too late that they are cannibals.

In Seattle, detective Quentin Conners is unfairly suspended and his partner Jason York leaves the police force after a tragic shooting on Pearl Street Bridge, when the hostage and the criminal die. During a bank heist with a hostage situation, Conners is assigned in charge of the operation with the rookie Shane Dekker as his partner. The thieves, lead by Lorenz, apparently do not steal a penny from the bank.

Further, they find that Lorenz is killing his accomplices.
