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

Sean's quest will send ripples through the lives of an eclectic band of strangers, including newly elected U.S. President Elias Martinez (Golden Globe nominee Blair Underwood, "In Treatment"); Sophia Maguire (Emmy Award nominee Laura Innes, "ER"), who is the leader of a mysterious group of detainees; and Leila's shadowy father (Scott Patterson, "Gilmore Girls"). Their futures are on a collision course in a global conspiracy that could ultimately change the fate of mankind.

Ian Anthony Dale ("Daybreak"), Clifton Collins, Jr. ("Star Trek"), Taylor Cole ("The Violent Kind"), Lisa Vidal ("The Division"), Bill Smitrovich ("The Practice"), and Emmy winner Željko Ivanek ("Damages") also star in the ensemble drama.

The Event is a production of Universal Media Studios and Steve Stark Productions. Evan Katz ("24") serves as executive producer/showrunner; Steve Stark ("Medium," "Facing Kate") serves as executive producer; Jeffrey Reiner (NBC's "Friday Night Lights," "Trauma") is director/executive producer; and Nick Wauters ("The 4400," "Eureka") is creator/co-executive producer.
