Batman returns to the Bat-Cave to mark another case closed while the police begin processing their new booking. But nothing is ever as it seems with the Joker as the Clown Prince of Crime begins to wreak havoc, brutally beating himself in the holding cell before spraying his fellow inmates with a hidden capsule of acid. But just when it seems as though things are settling down, the Joker uses his one phone call to contact Detective Shancoe's loving wife and convince her that she has contracted a terminal disease driving the poor woman to suicide.

While Shancoe rushes home to find his wife's corpse hanging from the ceiling, Batman begins to wonder if turning the green haired mad-man over to the police was such a good idea after all.
