A bridal shower gone bad quickly becomes the swiss of death, and grilled cheese shop owner Carly Hale must sniff out the suspect.

Winter in Balsam Dell is a snowy affair, and to add in some cheer after the holidays Carly's former classmate Klarissa Taddeo is hosting her extravagant bridal shower at the historic Balsam Dell inn. But when a double-booking throws some mold in the cheese, Klarissa is left scrambling. Dawn, the maid of honor and wedding planner, saves the day by moving the shower to her family's mansion and books Carly to cater the party. It seems the group is going to pull off the shower without a hitch.

That is, until Klarissa's fiancé crashes the event. She's furious with her groom-to-be and when a loud argument ensues, everyone is shocked by what they hear. When the groom is later found dead at the bottom of the stairs, his drink spiked with a hefty dose of poison, Carly must put her nose to the rind and save Klarissa from being suspect #1.

Because you know what they say: it's always the (almost) wife.
