Koni Waves introduces private detective Koni Kanawai, an ex-cop in Honolulu, Hawaii who worked her way through college as a dancer at the Apanapana Ballroom. When a drinking problem gets her booted from the force, Koni starts her own detective agency. With the aid of Pete, her surf-buddy; Krystal, a colleague from her dancing days; and Huko, the owner of her favorite watering hole, Koni encounters a series of supernatural events that leads her to discover a dark side of her island not seen in the usual tourist spots.
