Ride-share cab driver Eric begins his day like any other, responding to the many fares who hail him from their smartphones throughout the city. Hiding his depression due to a marriage that has long since grown cold, Eric entertains small talk and discusses his real job of real estate. He even finds his own notions of love and marriage challenged by one fare in particular -- a foreign man whose elusive ramblings seem to light the fire of Eric's own self-reflection. When Eric's day turns to night and he takes the evening's last fare, he finds himself face to face with the source of his troubles. His unsuspecting passenger is a man named Patrick who doesn't know this cab driver from any other. But when Eric recognizes Patrick as the man who is secretly sleeping with his wife, a series of events are set in motion which threaten the lives of everyone who sets foot inside the car.
