After exposing Cornello in Lior as a fraud, the Elrics are on their way back to report to Mustang about the incident. They stop at the town of Aquroya and get caught up in the manhunt for a talented cat burglar named Psiren, who uses her skills as an alchemist to repeatedly fool the local police. The chief police officer convinces the Elrics to capture Psiren, yet she tricks them three times for believing that she steals for the good of the people, seemingly saving certain buildings from being torn down. However, Psiren gets away with having a building getting demolished anyway. Al, still believing that Psiren is really a good person, tries to stop Ed from catching Psiren before she gets away with the loot. Ed is later able to catch Psiren, but she still makes an escape. Ed realizes her importance as a draw for tourism in the sinking city of Aquroya.
