Kim Hee Joo (Park Bo-young), a security guard at an international airport, finds her life turned upside down the day she stumbles into possession of gold ingots linked to illegal trafficking. Lust, betrayal and power struggles soon surround her, pushing her into a spiral where she must choose between morality and temptation.
At his side, Kim Sung-Cheol (Sweet Home, Arthdal Chronicles) plays Jang Wook, a gang member both protective and menacing, whose ambiguous intentions add constant tension to the plot. Lee Hyun-Wook (Mine, Remarriage & Desires) plays Lee Do Kyung, an airplane co-pilot with a double face: both in love with Hee Joo... and responsible for her involvement in the affair.
