When a rookie lifeguard claims he saw an apparition of a young girl  running through the surf in a white nightgown, everyone thinks he's  crazy. But when the lifeguard turns up dead after being drowned, Eddie  is haunted by the same apparition and it revives a painful memory of the  drowning of his sister. Meanwhile, Hobie attempts to babysit for a  friend's dog in his house without Mitch noticing.
