This film is an action-packed, rapid transit express that races along on its almost two-hour non-stop journey about mountain climbing, double-crosses and murder. The movie's opening rescue sequence is both thrilling and horrifying in its unfolding drama and sets the tone for the rest of the film. Gabe Walker is a believable hero, subdued and sensitive but tough in the clutch and gets a great assist from girlfriend Jessie who understands the reasons why Gabe is haunted by the demons of guilt. John Lithgow again is a suave villain, an evil mastermind who watches his master plan spin out of control as bad luck and bad weather conspire to thwart his grand design. Lithgow has plenty of help from a motley crew of killers and vicious types who try to outdo each other for sheer brutality and end up snarling at one another like the jackals they are. Great stunt work and Italian Alpine vistas add realism to the movie.
