Mysteriously ambushed and knocked out cold, the Titans wake to find themselves in the hands of Mad Mod, a British villain disgruntled by the Titans’ interference in other villains’ business. Separated from each other, the Titans make their way back to each other one by one while dealing with robots and optical illusions. They catch up with Mad Mod, only to be recaptured one by one. Robin manages to escape capture and find Mad Mod. As Robin fails to even touch the villain, he decides upon a different approach. He passes through all the illusions and reaches the operation center, where he apprehends an elderly Mad Mod.
