Three old high-school friends meet after a long time apart and get drunk. When Min-woo – who comes from a rich Korean family – falls asleep, Jun Seong and Jea Hyo put him to bed, then answer a call from home on his cell phone. They pretend to be his kidnappers – “We have your son! Prepare a billion won!” – but the game soon becomes terribly real as it turns into plan, a ransom materialises and Min-woo realises how he is being used. Not that he is a pushover, as his former friends will discover when he becomes their accomplice. The twists and turns as the three of them try to score the perfect deal keep the thrills coming and the stakes escalating.
