Based on the documentary of the same name, Freeheld tells the true story of Laurel Hester (Julianne Moore), a police officer with terminal cancer fighting to get her partner, Stacie (Ellen Page), access to her pension benefits in pre-marriage equality America.

The story is both emotionally gut-wrenching and historically significant—and will likely get mondo Oscar nods.

Directed by Peter Sollett (Nick and Nora’s Infinite Playlist) and written by Ron Nyswaner (Philidelphia), Freeheld also stars Michael Shannon, Luke Grimes and Steve Carrell.
