The Joker plans to become the king of surfing, hoping the fame will give him control over the hearts and minds of Gotham City. He captures top surfer Skip Parker, then uses his "Surfing Experience & Ability Transferometer" to transfer the needed skills and stamina from Skip to himself. When all the other contestants drop out of the upcoming surfing match, Batman steps up to challenge the Joker's supremacy.

Commissioner Gordon travels across the channel to Londinium by request of the President to assist in a spree of baffling burglaries. Also aboard ship are Bruce Wayne, Dick Grayson, their manservant Alfred and Gordon's daughter Barbara. Alfred sets up a make-shift Batcave under a rented mansion near Londinium while Batman & Robin visit lord Ffogg and Lady Peasoup, who run a girl's finishing school that teaches their students a degree in shoplifting.

Lord Ffogg and Lady Peasoup plan to steal a ship-worth of mod clothing material with which they can control the fashion world of Londinium. Ffogg and his men subdue Batman, Peasoup and her girls grab Robin and Lady Prudence uses the paralyzing fog on Batgirl.

Batman, ably assisted as always by Alfred, saves Robin from being crushed by a winch at the Tower of Londinium. He also rescues Batgirl from the dungeon at Ffog Place. But Robin gets stung by an African Death Bee as Lord Ffogg and Lady Peasoup get ready to steal the crown jewels at the Bloody Tower.
