Runaway Train

Manny (Voight) is the toughest convict in a remote Alaskan prison who, along with fellow inmate Buck (Roberts), makes a daring breakout. Hopping a freight train, they head full-steam for freedom, but when the engineer dies of a heart attack, they find themselves trapped, alone and speeding toward certain disaster. Until, that is, they discover a third passenger, a beautiful railroad worker (Rebecca DeMornay) who's just as desperate and just as determined to survive as they are! (official distributor synopsis)
