Richard Widmark plays a hardened cold-war warrior and captain of the American destroyer USS Bedford. Sidney Poitier is a reporter given permission to interview the captain during a routine patrol. Poitier gets more than he bargained for when the Bedford discovers a Soviet sub in the depths and the captain begins a relentless pursuit, pushing his crew, and the on-screen tension, to breaking point in this chilling cold-war tale of cat and mouse.
