The Good Mother is a 1988 American drama film and an adaptation of Sue Miller's novel of the same name. Directed by Leonard Nimoy, the film stars Diane Keaton and Liam Neeson in the leading roles. The Good Mother explores feelings and beliefs about children's exposure to adult sexuality and challenges society's growing reliance upon courts to settle complex private and ethical matters.
Anna Dunlap (Diane Keaton), is a piano teacher who works part-time at a college laboratory and a recent divorcee who has custody of a four-year-old daughter. She meets and falls in love with Leo (Liam Neeson), a sculptor who helps her to find true passion and fulfillment. But her sexual liberation comes at a very high cost: her ex-husband Brian (Naughton) questions her new lifestyle. Worse, he accuses Leo of sexually molesting Molly and sues Anna for custody of their daughter.
