Synopsis:

Thanks to Ellie, Mister Muscle is freed from all charges in court as she can prove that Ralph Bartoli was murdered by his own lawyer, Eric F. Schuster.
Meanwhile, the man behind the recent attacks on Hero Hotline is revealed as the super-villain called the Calculator. He takes out the Hotline members one by one, then attacks the Hotline HQ to get his revenge on the Coordinator. However, the Hotline members have a few tricks up their proverbial sleeves, and defeat the villain.
Other events include Fred appearing on the Alberto Rosario show, and Marie the Psychic Turtle is reported to be pregnant.
