High Tide (1987)

Synopsis
Gillian Armstrong directed this powerful and moving film containing a brilliant performance by Judy Davis. The story takes place in the small New South Wales seaside village of Eden. Davis is Lillie, who is renting a run-down trailer as she waits for her car to be repaired. One night, when Lillie is drunk and cannot walk from the toilet block back to her trailer, a teenage girl, Ally (Claudia Karvan) -- who lives with her free-spirited grandmother Bet (Jan Adele) in another trailer in the trailer park -- helps her back home. Lillie and Ally become good friends, and it is only when Lillie finally meets Bet that she realizes that Ally is, in fact, her own daughter, who she abandoned years earlier after the death of her husband. ~ Paul Brenner, All Movie Guide
