Ava, an ordinary college girl, is forced to break up with her wealthy boyfriend Logan by his mother Victoria, who only offers a ten-dollar breakup fee. Ava cuts off the relationship without hesitation. She accidentally travels to a parallel world where currency values are extremely low, and her savings turn her into a millionaire overnight. No longer humble, she returns all gifts from Logan in public and stands up to her bullying roommate Madison. She wholeheartedly supports her shy, acting-loving younger sister Lily. When shopping, she treats junior staff kindly and mocks snobby salespeople who judge customers by appearance. She splurges on luxury real estate and invests in a fantasy drama series to secure a core role for Lily. Logan is obsessed and keeps pestering her, while his mother keeps creating trouble. A creepy admirer and a rich girl who buys acting roles also stir up conflicts. With massive wealth, Ava stays calm and composed. She breaks class prejudice with her own strength, protects her family, and hits back at all disdain and harm gracefully.
