Scam (released theatrically in the Philippines as Restless Heart) is a 1993 television film adaptation of crime drama novel by Craig Smith titled Ladystinger.
Maggie Rohrer (Lorraine Bracco) is a seductive con-artist scamming the rich in Miami Beach.
When she picks the wrong mark, Jack Shanks (Christopher Walken), he blackmails her into working with him on the ultimate scam in Jamaica.
He claims no knowledge of the money, she distrusts him, he's using her, things start getting dangerous and even murderous - and then her boyfriend shows up.
Miguel Ferrer and Martin Donovan are also first-rate talents, but Lorraine Bracco was clinically depressed at the time, having trouble with her boyfriend Edward James Olmos and her ex-husband Harvey Keitel.
