Carol Mills (Peggy Lipton) is a mother who has a troubling relationship with her 19-year-old daughter Annie (Danica McKellar). Unable to live with her any longer, Annie moves out and marries her boyfriend Ken Carman (Martin Cummins). It soon turns out their marriage is a failure, and she decides to move in with another family, George and Helen Preston (Terry David Mulligan, Susan Ruttan). Not much later, Carol receives a message, informing her that her daughter accidentally died. Crushed, she learns at the funeral that Annie had a life insurance policy worth of $100,000, with Helen as beneficiary. She starts to suspect that Annie was actually murdered because of that and tries to collect evidence, with the help of a detective (Bruce Weitz).
