Lee Jung-yoon is a woman at the end of her twenties… and the end of her tether. Working every hour of the day to scratch out an impoverished living, her thankless jobs as a post office worker and a garage cashier have her going nowhere fast. At least, that is until she is confronted in the street by Jun-woo, a mysterious loner who predicts death. His latest vision is of Jung-yoon’s grisly demise at the tattooed hand of an unseen man, right at the moment she turns 30. Is Jun-woo the saviour who can help her escape her destiny, or the devil leading her into a deadly trap? With only 6 hours left, can she survive her impending doom?
