Ultraman, a giant alien from the Land of Light in Nebula M78, enters Earth's atmosphere in pursuit of an escaped space monster. In the skies above Japan he accidentally crashes into a Jet VTOL piloted by Hayata, a member of the Science Special Search Party (SSSP), an international research and defense agency that protects the world from monsters and aliens of all shapes and sizes. To save Hayata, Ultraman merges his life force with the dying human and vows to stay and fight for peace on Earth. Now, whenever the Patrol faces a threat too great for them to handle, Hayata transforms into Ultraman to save the day!
