Cary Grant stars as the one sane member of a charmingly lunatic family in director Frank Capra's classic comedy. When Mortimer Brewster (Grant) brings his new bride to meet his two kindly aunts, he discovers that, among many other acts of charity, the two genteel ladies help lonely old men die happy ... by feeding them a wonderful meal before poisoning them. Now, Mortimer desperately wants to protect the two serial murderers he loves, stop them from killing anyone else and keep his bride from discovering how deranged his family really is.
