This rugged adventure takes sibling rivalry to new heights when a luxury airliner crashes into the side of a mountain. Young, brash Robert Wagner, in one of his earlier roles, is determined to climb the treacherous peak in an effort to plunder the craft. Spencer Tracy, as his soft-spoken superstitious and sensitive older brother, is horrified by his brother's quest. Yet, he also knows that without his help his brother will not survive the climb. Filmed on location in the French Alps, this breathtaking feature boasts terrific performances from both Tracy and Wagner.
