The story happens in the near future, sinister aliens and giant monsters constantly threaten civilization during this period. The only Earth organization equipped to handle these disasters is the Science Special Search Party (SSSP) also known as the Science Patrol, they are always ready to protect Earth from this threat.
When the situation becomes desperate, Shin Hayata, the Patrol's most capable member, holds the key to salvation in the form of the "beta capsule," which, when ignited, allows him to transform secretly into the super-humanoid-powered giant from space, who becomes known to the people of Earth as Ultraman!
The series ran for 39 episodes from July 17, 1966 to April 9, 1967.
