When a satellite accidentally crashes into the jungle, Jenner asks Rio to accompany the recovery team on their retrieval mission. One of the expedition members is Dr. Marie Deschaux, the sexy French scientist who designed the satellite. Marie has ulterior motives for wanting to get to the satellite so quickly: she has secretly used plutonium in the satellite, so she is intent on killing everyone who finds out. Rio reluctantly has to help her find it before the plutonium kills thousands of innocent people.
