Tony Kirby has fallen in love with Alice Sycamore. All that's left is for the families to meet each other. Unfortunately, Tony's parents are prim and reserved while the Sycamores are a little more unconventional. There are fireworks, a printing press, Russian emigrants, ballerinas, some kittens and even a snake or two in the Sycamore household. When Tony brings his family to dinner on the wrong night, mayhem follows.
