Compromise (1925)

A woman of high morals, Joan Trevore expects to find in her marriage to Alan Thayer the happiness that has long eluded her. She and Alan are still on their honeymoon, however, when Nathalie Trevore, Joan's spoiled and selfish younger sister, sets her cap for Alan and successfully vamps him. Alan later boards a yacht for a business appointment and is "shanghaied" by Nathalie and her friends, who take him ashore so that Nathalie may triumph over Joan at the honeymoon cottage. Joan horsewhips Nathalie. A cyclone wrecks the cottage, and Alan saves Joan's life, leading to a reconciliation between them.
