Ironside: The Last Cotillion on AllMovie

Aging socialite Athena Champion (Kim Hunter) desperately seeks out the aid of her friend Chief Ironside (Raymond Burr). Several elderly men have recently been murdered--all of them old boyfriends of Athena who had attended her debutante's ball. Suffering from the early stages of Alzheimers', Athena is worried that she may have killed the victims without knowing it--and she wants Ironside to determine whether she is innocent or guilty.
