Two and a half weeks ago magazine crafts editor Anastasia Pollack arrived home to find Ira Pollack, her half-brother-in-law, had blinged out her home with enough Christmas lights to rival Rockefeller Center. Now he's crammed her small yard with enormous cavorting inflatable characters. She and photojournalist boyfriend (and possible spy) Zack Barnes pack up the unwanted lawn decorations to return to Ira. They arrive to find his yard the scene of an over-the-top Christmas extravaganza. His neighbors are not happy with the animatronics, laser light show, and blaring music creating traffic jams on their normally quiet street. One of them expresses his displeasure with his fists before running off.

In the excitement, the deflated lawn ornaments are never returned to Ira. The next morning Anastasia once again heads to his house before work to drop them off. When she arrives, she discovers Ira's attacker dead in Santa's sleigh. Ira becomes the prime suspect in the man's murder and begs Anastasia to help clear his name. But Anastasia has promised her sons she'll keep her nose out of police business. What's a reluctant amateur sleuth to do?
