Synopsis:
While on a fishing trip with his uncle Desmond, Danny Dennis locates the boat of missing scientist Professor Slater on a small island. The group goes ashore and is attacked by a giant cat and a giant man-sized rat. Rex helps the humans escape and locates Professor Slater. The professor explains his experiment with a Delta Ray which causes the enormous animal growth. A leg injury prevents him from reaching the device to turn it off. Desmond and Rex reach the Delta Ray, fighting off giant animals along the way. Once the device is shut off, the animals are restored to normal size. Fearing the device is too dangerous, Slater drops it into the ocean.
