18 Stunden bis zur Ewigkeit (Juggernaut)

An anonymous extortionist claims to have planted several bombs aboard the passenger liner Britannic, which is crossing the North Atlantic with around 1,200 people on board. He demands a large ransom and threatens to detonate the explosives if his demands are not met. With rough seas making evacuation impossible, a team of experienced bomb disposal experts, led by Richard Harris's character, is flown to the ship. As they race to locate and defuse the deadly devices, police on shore work desperately to identify and capture the mysterious bomber. What follows is a tense, gripping race against time.
