GOTHAM city skyline; Sunset; autumn: Gothic towers of granite and glass shimmer golden in the late day sun. A crime wave has swept Gotham since someone escaped unnoticed, leaving its citizens with just one last hope - Batman."

At every scene of crime, the detectives have found no clue, except a number card. Bruce Wayne, meanwhile, has been getting similar cards at his address over the past few days. BRUCE: "The letters I'm getting match those found at the crime sites. Why would anyone be sending me these riddles?" Bruce is standing before the city map in the Bat Cave when Alfred enters with horror written on his face. ALFRED: "They took away Master Richard. What if they find out that he is Robin; they'll kill him and know your secret. The thugs left this number card for you."

BRUCE: "Whoever is doing this is connected to these riddles." He moves to a table where the riddles are spread before him, including the most recent one. BRUCE: "These numbers are the answers." ALFRED: "This puzzles me - 1, 3, 1, 8 and 5. What do these mean?" BRUCE: "What do maniacs always want?" ALFRED: "Recognition, of course." BRUCE: "Precisely; so, this number is probably some kind of calling card." Bruce stares at the numbers. Adds these: 18. Squares these: 1916425. No luck. Starts again, separating these: 13/18/5. BRUCE: "Letters in the alphabet." ALFRED: "Of course. 13 is M....MRE." BRUCE: "How about, MR. E." ALFRED: "Mystery." BRUCE: "Another name for Mystery?" ALFRED: "Enigma." BRUCE: "Exactly. Mr. E. Mister Edward Nygma, The Riddler, he must have..." NEWSCASTER (on TV): "Some of the inmates have escaped from the Arkham Asylum for the Criminally Insane…"

BRUCE: "Claw Island. Nygma's headquarters. I'm sure that's where they're keeping Robin." Batman flies in through a window, kicking a row of thugs down before he lets go his rope and lands on the floor. EDWARD (The Riddler): "Bruce, babe, I gotta be honest. My entrance was good. Your was better." A huge thug charges at Batman. Batman heaves him overhead, throws him, crashing, into a display of stacked boxes. RIDDLER: "Riddle me this, where could I have kept your sidekick?" Presses a switch, revealing Robin in a glass cage, with a time bomb ticking at his chest. The door has two knobs, labelled "left" and "right". RIDDLER: "Now, riddle me that, a weight of 11,111 g is placed on the right hand plate of a balance. Someone places weights on the two plates of the balance; the first weight is 1 g; and each successive weight is twice as heavy as the previous one. At some moment, the two plates are in equilibrium. Where was the 16 g weight placed (on the left or on the right)?" Will Batman be able to solve the riddle or is it the end of Robin. Calling Batman; solve the riddle and save Robin.
