When a scientific procedure has unexpected results, Rory tries to make the best of a bad situation and ends up becoming an accidental superhero. Medical scientist Rory is working in his top secret underground laboratory in Central London when a procedure has unexpected results. Far from curing his patient, a monkey called Arnold, of an unpleasant disease, he manages to turn the animal invisible! In his panic, Rory accidentally gets some of the serum he injected Arnold with into his own bloodstream, rendering himself invisible, too. With disbelief and confusion filling his brain, Rory finds it impossible to think straight, much less to figure out what precisely happened, and what on earth he’s going to do about it. So, after stripping off his clothes—which remain visible and therefore would give him away—he heads out into the London night for a walk to try and clear his head. Soon, a series of events lead him into a situation where he takes heroic action to protect somebody from hurting themselves, or someone else. And, just when Rory thinks things can’t get any weirder, he’s found, completely naked, in the home of the man he helped the previous evening. How can he explain his way out of this?
