Cassandra

Ben Costigan is having nightmares about his son being killed. While out for a walk, a woman on the grounds of a mental hospital comments that his son is going to die. Going into her dreams turns out to be difficult because she is schitzophrenic, but she predicts the murder of an insurance salesman so Ben starts taking her seriously. She shows the Sleepwalkers that the death of Ben's son is going to happen at a hospital, but can they find the right hospital in time?
