Mitch receives a call that Caroline needs all available assistance during a rescue. Apparently a young girl named Rosanna is missing. Her mother Lucinda is real worried, but she doesn't speak any English, just Spanish. When Many finally arrives to the beach, he translates everything Lucinda says. When Manny asks Rosanna's younger sister Nikki what happened, she tells Manny that Rosanna was very sad and that she waited for the lifeguard on duty, Cody, to leave his tower. When Cody left to meet Lani at the movies, Rosanna went into the water, and Nikki never saw Rosanna coming out of the water. Mitch organizes a search unit. All available lifeguards are sent to the beach. J.D. and Sheryl have been out on surfboards but couldn't find anything. Later Manny finds out that Cody left his tower 4:57 p.m., not 5 p.m. This upsets Mitch who doesn't like when a lifeguard leaves the tower early. Meanwhile, Cody meets with Lani and she tells him that she just got a call from headquarters. All lifegu (thetvdb.com)
