It's 5p.m. An unseen news reporter declares that a press conference is being interrupted by something strange. Blurry news footage documents the chaos: people running for safety, a loud buzz filling the air, and harsh winds overturning furniture. As the reporter screams, "Run!" the footage abruptly stops. It's 23 minutes earlier, and an L.A.-bound flight readies for takeoff from the Miami Airport. A flight attendant asks a sweaty, anxious-looking Sean Walker to exit the bathroom and take his seat. A discarded maintenance uniform peeks out of the trash. Sean nervously makes his way to his seat, and sees shadowy men rushing through the airport, intent on finding him. As the plane picks up steam, a black SUV races alongside it, just off to the side of the runway. Sean regards it with caution.
