Laura Innes stars as Sophia Maguire, the leader of a mysterious group of detainees being held at a top-secret facility. She becomes a critical liaison to President Elias Martinez (Blair Underwood) amidst a huge government cover up, in NBC’s new high-octane conspiracy thriller “The Event.” Recognized for her talented work in front of the camera as well as behind the lens, Laura Innes is a three-time Emmy Award nominated actress and director. Innes is best known for her work as the skilled but abrasive Dr. Kerry Weaver on the long-running hit show “ER.” She joined the acclaimed NBC medical drama in its second season, and her recurring role led to being cast as a series regular at the start of the third season. She received two Emmy nominations for her portrayal, as well as three Screen Actors Guild Awards as part of the “ER” ensemble, and has received five nominations for Best Supporting Actress from Viewers for Quality Television. In January 2007, Innes left “ER” after 12 seasons, becoming the longest-serving cast member in the show’s history. She returned to “ER” for two episodes (including the series finale) during the series’ 15th and final season. "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.
