The proprietors of A Little Taste of Heaven, their Longely, N.Y., catering company, prepare a Thanksgiving feast for Scrooge-like fireworks manufacturer Monty Field and his family at the Field mansion. When Monty comes into the kitchen to test the roasting turkey, Bernie and Libby watch in horror as Monty taps the pop-up button in the bird's breast and the turkey explodes, blowing off the top of his head. Libby fears their stuffing made the turkey explode, but they soon learn that there was plenty of rivalry among the assembled family members, any one of whom had reason to want Monty dead. A heavy snowstorm ensures the suspects stay put as the sisters start to investigate. That their father, Sean, was on bad terms with the victim complicates their task. The action builds to more fireworks and a dramatic rescue.
