🌞 A GLAMOROUS ISLAND MANOR

Widow Mimi lives on idyllic Mackinac Island, where cars are not allowed and a Gibson martini with three onions at the witching hour is compulsory. Her estranged granddaughter, Addie, is getting over the heartbreak of not only being dumped by her fiancé, Brian, but also being cut out of the deal for the brilliantly successful video game Murderscape they invented together (with Addie doing most of the heavy lifting).
When Mimi gets an invitation from local socialite Jane Ireland-a seventysomething narcissist who's having a salacious affair with her son-in-law-to a charity auction, she invites Addie. But Mimi doesn't tell her that a blackmail threat from Jane looms over the party's invitation.
Once they arrive, a big storm rolls in, trapping everyone in the mansion. And then, Jane is murdered. Soon Mimi and Addie's strained relationship is put to the test when they must team up to narrow down the suspects. When another body turns up, the sleuthing pair realize someone else is playing a deadly game, and they might not survive the night.
