Following a critically acclaimed first season, Mary Kills People season two will premiere on Lifetime on 12 March. The provocative drama series follows Mary Harris (Caroline Dhavernas), an ER doctor who helps people die with dignity.

The drama picks up eight months after Mary and Des (Richard Short) framed Grady (Greg Bryk) for the deaths of their patients. The mysterious Olivia Bloom (Rachelle Lefevre) approaches the pair with a deadly request, instigating a chain of events that unfold over the course of the season.

Ahead of the season premiere, a full season one marathon will air on Lifetime Movies on 11 March.
