The Long Kiss Goodnight (1996)

Samantha Caine, suburban homemaker, is the ideal mom to her 8 year old daughter Caitlin. She lives in Honesdale, PA, has a job teaching school and makes the best Rice Krispie treats in town. But when she receives a bump on her head, she begins to remember small parts of her previous life as a lethal, top-secret agent. Her old chums in the Chapter are now out to kill her so she enlists the help of a cheap detective named Mitch. As Samantha remembers more and more of her previous life, she becomes deadlier and more resourceful. Both Mitch and Charly proceed to do the killing thing, the bleeding thing and the shooting thing.
