Tragicomic road movie set during the Edo period. It follows a samurai, his two servants – including spear-carrier Genpachi – and the various people they meet on their journey, including a policeman in pursuit of a thief, a young child and a woman who is to be sold into prostitution.
Hayata is a member of the Science Patrol, an organization tasked with investigating bizarre anomalies. He is mortally wounded when accidently encountering an alien being from Land of Light, who grants Hayata new life as the two are merged into one. Now, whenever a threat arises that is too great for the Science Patrol to handle, Hayata activates the beta capsule and becomes the hero known as Ultraman.
A group of five law enforcers search Edo for a missing sword.
