Life Guardian

After Caroline, Neely, and Manny rescue three orphan teenage boys from drowning near a rock jetty, Caroline seeks out a mysterious youth who helps her rescue one of the boys, named Derek, who is connected with a street gang that means harm. It turns out that the youth is actually the ghost of Derek's long-dead brother, who's looking out for him since no one can see him except Caroline. Meanwhile, Neely's ex-husband, Peter, arrives, and she becomes confused again ever since she walked out on him two years ago.
