For mechanic Larry Stilson (Steve Bisley, Mad Max, The Great Gatsby) and his wife Carmel (Arna-Maria Winchester, Coda), a weekend in paradise turns into their most horrifying nightmare. At their retreat in an isolated mountain valley, they are confronted by Heinrich (Ross Thompson, Boulevard of Broken Dreams), the victim of a deadly nuclear spill who is in the throes of a horrifying radiation death. A top-secret government security team moves in with an army of vicious decontamination workers to seal off the valley, forcing Larry and Carmel to attempt a daring high-speed escape... But, the question growing more urgent by the minute is - can the radioactive waste be contained? Boasting high-octane car chases and spectacular stunts staged by George Miller, the director of Mad Max, and appearances from the stars of that film (Steve Bisley, Hugh Keays-Byrne and Mel Gibson), The Chain Reaction is a slick, futuristic action thriller that hurls you into the nightmarish world of terror and nuclear holocaust.
