The scientist Dr. Monja is interested in the legendary "Elixir of Life" which supposedly grants its users both immortality and eternal youth. He creates a "Time Tunnel" which allows a team of young agents to search for information across various time periods and dimensions. They regularly face the villainous Akudama trio which is also searching for the elixir. The villains are led by Muujo, a beautiful woman who wants to maintain her youth for as long as possible.—Dimos I
