'Black Lake' revolves around the failing marriage of Alana and her husband, Tom, following the recent miscarriage of their first child.

Alana's father, Jonathan, has invited them Upstate to celebrate the release of her sister, Clara, from a rehabilitation center for narcotics.

Jonathan's spontaneous decision to bring a new, and much younger, boyfriend along with him sparks discomfort, whilst Clara's sexual advances towards Tom, and Alana's worsening physical condition eventually plunges the weekend into chaos.

In this simmering no holds barred family drama, the truth of how they individually feel about one another cannot help but eventually rise to the surface.
