L.A.-based private detective Regan Reilly gets a call from her best gal pal, urging her to come to Hawaii for one last girls' weekend before Regan ties the knot with Jack "no relation" Reilly, and so she happily packs her bags. At the Waikiki Waters Playground and Resort, the body of Dorinda Dawes, the hotel's gossipy PR woman, washes ashore wearing a valuable lei that once belonged to a Hawaiian princess and was stolen from a museum in Honolulu thirty years ago. The resort manager doesn't believe that Dorinda drowned accidentally and persuades Regan to take on the case. The more she starts digging, the more danger she is in. Can Regan find out what really happened before it's too late for her and the other vacationers at the Waikiki Waters?
