Mia, a working-class Brooklyn lass, signs a 30-day deal to pose as the wife of billionaire heir Julian Sterling. In return for sabotaging his family’s arranged marriage, she will pocket a million quid. The moment she steps into Sterling Manor, she rips up its stuffy, draconian house rules. She exposes snobbish socialite Vanessa for exploiting staff, laundering money through sham charity events and framing innocent people. She also encourages Julian’s repressed younger sister Chloe to chase her dreams, and soon wins the respect of the family’s sharp-tongued matriarch. When the fake marriage contract comes to light, Mia leaves cleanly with no regrets. Julian abandons his billion-pound family empire without hesitation, tracking her down at her tiny Brooklyn burger shop.
