U.S. undercover agent Harry Wargrave has a straightforward assignment: escort a Soviet defector on Europe's Milan-to-Rotterdam train, then cross the Atlantic and deliver his charge to Washington like a package. Easier said than done. Commandos are out to stop Harry – and a new weapon may be deployed in this patriot game: a devastating avalanche. Veteran director Mark Robson (Von Ryan's Express, Earthquake) mans the controls and a first-class cast powers the excitement of this thriller that barrels through scenic locations and constant danger. Robert Shaw (Jaws) is the calculating, freedom-bound Marenkov. Academy Award-winner Lee Marvin plays dutiful, cynical Wargrave. And Linda Evans, Maximilian Schell, Horst Bucholz, Joe Namath and Mike Connors all earn their cloak-and-dagger badges as the story bullets from streets to iron rails to the sea. All aboard the Avalanche Express!
