Bette Davis plays artist Kate Bosworth
A Stolen Life on IMDB
Kate Bosworth (played by Davis) is an artist who misses her boat to an island off New England, where she intends to meet her sister and uncle. She persuades Bill Emerson (played by Ford) to take her home in his boat, and they both fall in love. However, Kate's twin sister Patricia (also played by Davis) decides to fall in love with Bill also, and she succeeds in stealing him away.
Refusing to be happy for Patricia, Kate instead focuses on her work. Bill eventually goes to Chile, allowing Kate to spend some time with her sister. They go sailing, and Patricia is washed overboard and drowns. Kate is washed ashore, and, when she regains consciousness, she is mistaken for Patricia. Being told that Bill is about to return from Chile, Kate decides to assume her late sister's identity.
