Kimo and Truck are sent to a remote location to help a scientist who is investigating several mysterious deaths by inhalation. Before long, Truck also shows signs of illness which he attributes to unknowingly violating a native curse (later revealed to be as a result of being exposed to plutonium on a previous assignment). The attractive doctor and Kimo hit it off, which makes both of them targets for the murderer, who is secretly harvesting coral from offshore and selling it.
