It's Halloween night in Lahaina, Maui, and the Mardi Gras of the Pacific is in full swing. But wedding planner Pali Moon isn't in costume--she's on a mission. A bridesmaid has vanished and Pali's canvassing Front Street, ducking into every overcrowded waterfront watering hole hoping to spot a girl with long red hair and a lingerie model's figure. No luck. Back at her car, Pali opens the door and finds the remnants of a bizarre trick or treat stunt. Turns out, Halloween in Lahaina isn't just a night for island high-jinx, it's also a night for vengeance.
