Woo-seok, the head of the family and a stuntman in his 40s, wants to go back to 1997, when he was at the best of his life in high school, before he got the scar on his face that put an end to his dream of becoming an actor. One day, he helps an unknown monk and buys five amulets that are said to change his life. By chance, his car crashes off a cliff while filming, and he wakes up as Woo-seok, the high school student he longed for in 1997. The project to remodel the first part of his life as a trashy father, son, and husband begins now.
