It's the wedding of the year. But someone won't survive it.
On a remote island off the coast of Ireland, guests gather to celebrate the wedding of Jules Keegan and Will Slater. Will is a rising television star, handsome and charming. Jules is a smart, ambitious magazine publisher. Though the sea is a little choppy and the cell service spotty, their wedding is everything you'd expect of a young power couple: designer dress, four-tiered cake, boutique whiskey, vintage champagne. Every detail has been curated to perfection. All that's left to orchestrate is the happiness.
But perfection is for plans, and people are all too human. It's not long after the cake is cut and the champagne popped that resentments and petty jealousies come out. Worse yet, the latest barometer reading shows the weather has shifted from FAIR to CHANGEABLE, and dark clouds are looming overhead.
Everyone on the island has a secret. Everyone has a motive. And someone won't leave this wedding alive...
