While Geneva Bay's upper crust gets ready to party down at a Prohibition-themed fundraiser, pizza chef Delilah O'Leary is focused on seeing her struggling restaurant through the winter slow season. The temperature outside is plummeting, but Delilah's love life might finally be heating up, as hunky police detective Calvin Capone seems poised to (finally) make a move.

But Delilah's hopes of perfecting a new "free-from" pizza recipe for a charity bash are dashed when a dead body crashes the party. Soon, Capone, Delilah, and her entire staff are trapped in an isolated mansion and embroiled in a dangerous game of cat and mouse.

To catch an increasingly-desperate killer, Delilah will have to top all of her previous crime-solving accomplishments, and a few pizzas, too.
