An adaptation of Elin Hilderbrands New York Times bestseller, The Perfect Couple follows Amelia Sacks (Eve Hewson), a bride marrying into one of Nantuckets wealthiest families. The grooms mother Greer Garrison Winbury (Nicole Kidman), a famous novelist, spares no expense on the high-society wedding. But, when a dead body appears on the beach, everyones Champagne dreams quickly vanish and are replaced by suspicion. As secrets bubble up to the surface, an investigation takes hold that feels plucked from one of Greers books.
