After a group of criminals kidnap the ballerina daughter of a powerful underworld figure, they retreat to an isolated mansion, unaware that they're locked inside with no normal little girl.
 
This movie doesn't kid around.
 
FUN FACT:  The abductors are given pseudonyms by the coordinator, Lambert, so that they don't know each other's real names in case one gets caught. These names are taken from The Rat Pack, the nickname given to a group of celebrities in the 1960s. They are Frank (Sinatra), Dean (Martin), Sammy (Davis Jr.), Peter (Lawford), Joey (Bishop), and (Don) Rickles. Comedian Don Rickles wasn't considered a fully-fledged member, but said "I never received an official membership card, but Frank made me feel part of the fun."
