Action-packed suspense thriller finds innocuous-looking purser Carter (Harris) the unlikely hero when the floating casino on which he works is hijacked by a heavily armed group of mercenaries, led by John Vernon. Complicating matters, a nuclear warhead has been smuggled aboard as collateral for a rendezvous with another ocean liner, loaded with gold bullion. A cast full of supernovas, dazzling set & stunt work, and a catchy theme tune by Jeff Wayne create a pleasing audio-visual experience light on logic but fast paced and entertaining nonetheless.

En un vaixell de càrrega convertit en un creuer, el primer oficial John Carter frustra el pla dels segrestadors internacionals d'utilitzar el vaixell com a esquer per a un vaixell del Tresor nord-americà que transporta lingots d'or.
