Mining heiress Summer Hayes bolts from a forced arranged wedding to Preston Locke, a reclusive industrial tycoon she has never laid eyes upon. Needing an escape, she drowns her sorrows at a quiet lounge and spends a reckless night with a charismatic stranger. When she arrives at Zenith Corporation to start a career on her own merits, she discovers her bar hookup, her stern executive boss, and her unseen legal husband are the exact same billionaire.
Rather than blowing his cover, Preston adopts a modest persona to assist Summer while dismantling corporate traps set by her cruel stepmother and opportunistic ex-partner. Supported by Preston's clandestine resources, Summer evolves into a ruthless business magnate, seizing control of her family's conglomerate. Summer must confront Preston's secret identity and decide if their accidental marriage deserves an authentic vow.
