Leila Buchanan (Sarah Roemer) is a beautiful young woman caught in the middle of a series of strange events on the NBC hit, "The Event". Life is simple for Leila at the beginning of the show. Her boyfriend, Sean Walker (Jason Ritter), takes her on a Caribbean cruise where he intends to propose marriage. Before he gets a chance to ask her to marry him, they meet a strange couple and their entire lives change.
Leila is kidnapped and taken to Texas. Her father, Michael Buchanan (Scott Patterson) is a pilot and is told that he must crash a commercial plane into a gathering where the President of the United States Elias Martinez (Blair Underwood) is attending or Leila will die. He plans on crashing the plane, despite Sean's attempts to stop him. Just before the plane hits President Martinez, it disappears from the sky.
Leila's life is spared, but she is still in danger. Sean hurries to Texas to find her and help her escape her captors. They flee to her childhood home, hoping to find some clues about who is behind the kidnapping. Sean and Leila work together to stay a few steps ahead of the covert agents that are chasing them. They also try to find her sister, Samantha (Anna Clark), who has also been kidnapped.
"I don't know who you are, but you're our only hope. My mother has been murdered. My father and my sister have been taken. Please. She's seven years old."
"Sean I'm taking you to a hospital. I am not losing you. I am not losing you."
