Chicago preservationists and architects face off against Northwestern University over the fate of the former Prentice Women's Hospital, a cloverleaf-shaped concrete tower designed by Bertrand Goldberg in the 1970s. The film tracks the public campaign to save the building as the university pushes to demolish it for a new research facility, with interviews from architects, historians, and city officials laying out both the structural engineering achievement Goldberg's cantilevered design represents and the arguments for tearing it down. Landmarks commission hearings, rallies outside the hospital, and archival footage of the building under construction fill out the record of how the fight played out in real time. The case becomes a stand-in for a larger question about how Chicago treats its Brutalist and late-modern buildings once their original purpose ends, and about who gets to decide what counts as worth keeping. The film follows the dispute through to its resolution, when the wrecking crews arrive despite the campaign built to stop them.
