Coup!

Isolated on a seaside estate, an entitled journalist (Billy Magnussen) and his socialite wife (Sarah Gadon) take in a mysterious grifter as a private cook (Peter Sarsgaard). When a plague descends on the island, the wily cook rouses his fellow staff to rebel and take over the mansion. Their employer suspects the cook’s coup is part of a more sinister agenda, and mind games between master and servant escalate into all-out class warfare.
