Matt and C.J. help a homeless man, former lifeguard John D. Cort, sleeping under a lifeguard tower. Depressed due to his increasing loss of eyesight, John finds a purpose for living when the potential donor for a 10-year-old boy with leukemia is reported missing. Mitch and John search for the seriously ill boy's missing brother, who drug smugglers force to dive a shipwreck for its cocaine cargo.
