When the SS Festivale sets sail from New York to France, its 3,000 passengers include Pulitzer Prize-winning author Harold Columbine and 146 members of the Church of the Cosmic Path, led by Father Craig Dunleavy, their charismatic messiah. Seizing control of the ship, Dunleavy demands $70 million in gold, intending to kill everyone onboard once its paid. Without knowing which passengers are cultists and warned that 12 will die for every hijacker harmed, Columbine and the captain search for a way to save 3,000 lives before Dunleavy makes good on his threat. Based on a novel by screenwriter Ernest Lehman, this mini-series was broadcast over three nights in November 1979.
