From the Chicago Reader (January 1, 1991). — J.R.

An engaging, exciting noir thriller (1952) set almost entirely on a train going from Chicago to Los Angeles, with a gruff cop (Charles McGraw) guarding a saucy prosecution witness (the underrated Marie Windsor). Richard Fleischer directed this nearly perfect B picture with no fuss and lots of grit and polish from a script by Earl Fenton; the capable cinematography belongs to George E. Diskant. 70 min. (JR)
