Serial killer Terry Spelling escapes from a mental institution and apparently meets up with an attractive young woman, Patty, on a train. When he tells her that he is an architect, she asks him to join her the next day and visit the run down old house she has bought with a view to renovating. Spelling agrees, but when Patty meets up with her architect she finds him curiously quiet and changed, as if he were a completely different man. What she doesn't realise is that perhaps there are in fact two Spellings.
