Plot

Eddie Kasalivich (Reeves) is a student machinist working with a team from the University of Chicago to create energy from bubble fusion. They have been trying for quite some time without success but Eddie, while working at home, discovers the secret to successfully using sonoluminescence to create stable bubble fusion. The next day in the lab, the machine is perfected by Eddie and everything appears to be working and stable. To celebrate, a party is thrown in the lab. That night after the party, Dr. Lily Sinclair (Weisz) tries to leave the lab but her car battery is dead. Eddie offers to take her home as she is obviously intoxicated, so they walk off in search of a taxi. Back in the lab, Drs. Alistair Barkley and Lu Chen are on their computers while a van is seen driving towards the lab. Chen hears a noise and goes to investigate, but is kidnapped by unknown assailants as Alistair also comes under attack.
