The summer solstice has arrived. Being the sun worshipers they are, Wildcat Crew heads to the beach for a day of fun and a picnic. But first, Marnie gets a huge surprise. Her parents have replaced her Camaro, destroyed in their first case. At the beach with thousands of other Southern Californians, the crew stumbles over a small, crying child. Instead of checking out the waves and working on their tans, they go on the hunt for the little boy's parents.
