The Winter Lake is a 2020 Irish-Canadian mystery drama film, written by David Turpin and directed by Phil Sheerin.

Tom is an introverted and troubled young man living with his struggling mother Elaine, the pair having just moved into a house that they have inherited.

Tom explores the nearby 'turlach', a winter lake fed by a mysterious and dangerous intermittently flowing underground river.

Elaine needs the help of her neighbour Ward, who jealously watches over his daughter Holly, a manipulative young woman who picks up on Tom.

[1][2][3] The words 'winter lake' in the title of the movie refer to a particular kind of water course that occurs in parts of Ireland, called in Irish a 'turlach'.
