Partners of Fate.

Helen Meriless, a serious young girl, marries a shallow man, while Frances Lloyd, a butterfly type, marries a level-headed engineer. Both start their honeymoon on the same ship. A shipwreck causes a mix-up of the married persons; Helen and her husband remain faithful to each other, but Frances and her husband separately engage in adulterous activities. A rescue ship carries away the faithless couple, leaving the others to their fate; but the latter survive and eventually triumph.
