Break & Enter (1999)

A cat burglar wakes the grandmotherly Phyllis when he breaks into her house, where she sleeps next to her husband, Eric. When she can't rouse Eric, she gets up alone and conks out the intruder with a frying pan. She strips off his clothes, puts them on, takes his keys and drives off into the night, leaving her nightgown. The intruder wakes and, for the next twenty-four hours, lives in an altered state.
