Batman: Arkham City
Cash positions his medical team, including Baker, in an abandoned church near the Solomon Wayne Courthouse. He and the medical professionals receive no assistance from the prison administrator, Dr. Hugo Strange, who provides only minimal medical care to the inmates. Instead, Cash is forced to beg Gotham City citizens for equipment and supplies. Bruce Wayne is the first to respond, donating security shutters for the church and body armor and supplies for the team. After discovering the external contributions, the furious Strange blocks the supply route, leaving the team on its own.
The Joker and his thugs capture the team inside the church in an attempt to force its doctors to treat his ailment. After Batman subdues the thugs guarding the team, Cash implores him to find Baker, identifying her as one of the good guys and telling him that she's been taken to another location in the city.
Despite her efforts, Baker is unable to readily devise a cure, so Harley Quinn and the Joker imprison her within the Sionis Industries Steel Mill to intimidate her into complying with their demands after initially considering using Mr. Hammer to execute her. However, before they are able to severely harm the restrained doctor, Batman breaks into the mill and rescues her. Afterwards, she informs Batman that the toxin in the Joker's blood is killing him, and that he blames something called "Titan." Batman instructs her to remain in the mill for her own safety.
