The Event

The Event is an emotional, high-octane conspiracy thriller that follows Sean Walker (Jason Ritter), an everyman who investigates the mysterious disappearance of his would-be fiancée Leila (Sarah Roemer), and unwittingly begins to expose the biggest cover-up in U.S. history.

The series, which premiered on NBC in Fall 2010, also stars Blair Underwood as U.S. President Elias Martinez; Sophia Maguire as the leader of a mysterious group of detainees; and Scott Patterson as Leila's shadowy father. Their futures are on a collision course in a global conspiracy that could ultimately change the fate of mankind.

The network canceled the series after just one season.
