Caitlin FitzGerald (“Masters of Sex”) stars in Mercy, a home invasion thriller from director and Buried scribe Chris Sparling for Netflix. She joins a cast that includes James Wolk (“Mad Men”), Tom Lipinski (“The Following”), Michael Godere (“The Affair”), and Dan Ziskie (“Treme”).

Mercy follows four estranged brothers gathered together at their childhood home to care for their dying mother. The bros get all kinds of emotional as family secrets are revealed up until the home invasion happens and things get good… we assume.

FitzGerald is best known for playing William Masters’ wife Libby Masters on Showtime’s original series “Masters of Sex.” Netflix will release the film in theaters and exclusively on their streaming service.
