 Mitch reluctantly attends his 20-year high school reunion at West Palisades High School where his ex-wife, Gayle, is also in attendance and becomes acquainted with him for a trip down memory lane, which is interrupted by an attempt to rescue an old nemeses buried up to his neck on the beach by two former geeks after a joke that goes wrong... and a rising tide which threatens to drown the guy. Meanwhile, Eddie finds an abandoned baby under his lifeguard tower with a note to take care of the baby for 24 hours, and Shauni has to be his coach to care for it the proper way.
