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.
