The 3D melodrama Dangerous Mission starts off with a bang when innocent Piper Laurie inadvertently witnesses the murder of her gangster boss. Though she doesn't get a particularly good look at the killer, she knows she's dead meat if she remains in town. Thus, Laurie skeedaddles to Montana's Glacier National Park, where most of the film takes place. Following her westward are Victor Mature and Vincent Price. One of these men is a federal agent, bound and determined to bring Laurie back to the East to testify; the other is the murderer, who intends to silence our heroine for keeps. Laurie doesn't know which is which, but the audience does. A bit poky at times (thanks in part to the uninspired editing of Gene Palmer), Dangerous Mission roars into life during a mid-film forest fire and a climactic chase through the glacier fields. Featured in the cast are William Bendix as a Montana
