Helena is thrilled when her best friend from high school, Sandra, returns to New Gotham, but the Birds are troubled by a series of murders with the unmistakable mark of Batgirl's nemesis, Lady Shiva. Determined to fight Lady Shiva as an equal, Barbara dusts off her Batgirl costume and experiments with technology that allows her to leave the wheelchair.

Citizens of New Gotham are being turned into clay by a villain whose crimes are similar to those of Clayface, the master of shape-shifting who has been in Arkham Asylum for many years. Helena confronts Clayface and learns that his son, Chris, is responsible for the new rash of crimes. She also finds out who was responsible for her mother's murder.

Harley Quinn acquires the power to hypnotize others with her eyes, and persuades Helena to reveal the secrets of the Clocktower, along with Barbara's and Dinah's true identities. She soon has all the ammunition she needs to wreak havoc on The Birds as well as the rest of New Gotham.
