Synopsis:
When medieval scientist Roger Bacon discovers that time travellers from the future have visited the past on at least three occasions, he develops a system to hypnotically send his assistants into the future to find them. The assistants, Marcus and Guy Tiller, are garbed as Batman and Robin, since Bacon has deduced that all men from the future must dress that way.

Marcus and Guy arrive in the present and are mistaken for the real Dynamic Duo. Batman and Robin spot the dopplegangers and follow them to learn what they are up to. When they do discover the truth, they befriend the time travellers.

Batman and Robin leave their new friends behind when they pursue a gang of speedboat bandits. However, Marcus and Guy see the Batplane crash on the television, so they go after the bandits themselves. Both sets of heroes locate and stop the bandits. Marcus and Guy then return to their own time with the knowledge that the future is a remarkable and worthwhile place.
