Early one morning, Lee Gulliver sees a sobbing woman throw herself into the ocean. Lee hauls the woman back to the surface, but instead of appreciation, she is met with fury as Lee has thwarted her one chance to escape her life. Bonded by disparate but difficult circumstances, the women soon strike up a close and unlikely friendship. Then one day, Hazel makes a shocking request: she wants Lee to help her disappear. But Lee soon learns that nothing is as it seems, and that Hazel may not be the friend Lee thought she was.
