Some unknown maniac is threatening a navigation company to blow up one of its luxury transatlantic liners, the "Britannic", now in high sea with one thousand two hundred passengers. He is asking for a five hundred thousand pound sterling ransom, otherwise the seven bombs aboard will explode. An experienced anti-bomb squad is sent to the "Britannic", but although all the bombs are located, a very high skill level will be necessary to dismantle them. Perhaps that task is impossible.

Juggernaut is a 1974 British crime suspense film starring Richard Harris, Omar Sharif, and Anthony Hopkins. The film, which was directed by Richard Lester,was largely shot on location aboard the TS Hamburg in the North Sea. It was inspired by real events aboard QE2 in May 1972 when Royal Marines and Special Boat Service personnel parachuted onto the ship because of a bomb hoax.

In the film, Richard Harris leads a team of Naval bomb disposal experts sent to disarm several large barrel bombs that have been placed aboard an ocean liner crossing the North Atlantic. Meanwhile, ashore, the police race against time to track down the mysterious bomb maker, who calls himself "Juggernaut", who will agree to a ransom in order to reveal the information that will disarm the bombs.
