In the midst of World War II, as the tide turns against the Axis, a German U-boat crew is sent out to patrol the Atlantic and fire at Allied ships bringing supplies to England. The submarine also carries a press correspondent, there to report from the front lines of nautical warfare. Meanwhile, the crew's captain (Jürgen Prochnow) is becoming disillusioned with the Nazi regime and with war in general. What starts out as a routine mission is soon livened up beyond the crew's expectations when their boat's surprise attack on a convoy is thwarted by a fast-moving destroyer. Battered by depth charges, the crew must pull together to survive the attacks of their unseen enemy. Widely considered to be director Wolfgang Petersen's best film and one of the finest German films ever made, DAS BOOT is stunningly realistic in its portrayal of the cramped conditions aboard a German submarine. Based on a novel by Lothar G. Buchheim, it is a striking example of an intelligent antiwar film clothed in the guise of a military thriller.
