No production unit at Paramount Pictures was busier in 1944 than the Pine-Thomas unit-and few were as bankable at the box-office. In Pine-Thomas' Dangerous Passage, Joe Beck (Robert Lowery), an easygoing resident of Central America, is summoned to Texas to claim his share of an inheritance. Making the journey by boat, Beck finds himself the target of several attempts on his life. He also forms a more than professional relationship with his attorney, Nita Paxton (Phyllis Brooks). En route to Galveston, Beck and Nita are shipwrecked and forced to swim for their lives. The identity of their mystery assailant is revealed in the last reel, though for a while it doesn't look like either the hero or the heroine will survive long enough to profit from this knowledge.
