Suddenly, Last Summer is a 1959 mystery film based on a play by Tennessee Williams and starring Elizabeth Taylor and Katharine Hepburn. Catherine Holly (Elizabeth Taylor) is committed to a state hospital for mental illness after she and her cousin, Sebastian Venable, take a trip to Europe that ends in Sebastian's death. Sebastian's mother, Violet Venable (Katharine Hepburn), knows a terrible secret about her late son and is determined to protect his reputation at any cost. Afraid that Catherine will reveal the truth about Sebastian's death when she gets better, Violet offers to fund a new hospital wing if Dr. John Cukrowicz (Montgomery Clift) performs a lobotomy on Catherine. After examining his patient, however, Dr. Cukrowicz begins to doubt that she needs the operation and becomes suspicious of Violet's motives. Dr. Cukrowicz eventually administers a truth serum to the young woman, hoping to draw out the shocking details of Sebastian's death.
