The film is adapted from a true story. It tells the story of a couple who came to an isolated island to find a restaurant after seeing food information on the Internet, but encountered many unexpected crises. According to statistics released by the National Police Agency in 2015, there were as many as 110,000 cyber crimes in 2014. Most of them were online financial fraud and hacking, but there were also serious criminal crimes such as murder, rape, and serial murder committed through the Internet. In particular, the number of victims who were deceived by many untrustworthy information on the Internet without any suspicion is increasing. In particular, the use of smartphones and apps has become an indispensable part of our daily lives, so cyber crimes are actually very close to each of us. "The Trap" is also based on this intention, hoping to tell the audience that in fact, everyone may fall into such a trap. In the film, the couple "Jun Shik" and "So Yeon" played by Jo Han-sun and Kim Min-kyung came to the isolated island to find a restaurant with a good reputation on the Internet. They met the restaurant owner who was a little too friendly, but then fell into an unexpected trap. The film's director, Quan Hyung-jin, won the 44th Grand Bell Award for Best New Director for "For Hogwarts" and was nominated for the Best Film at the 10th Shanghai International Film Festival and Asian Newcomer Awards. Ma Dong-seok, who used to play villains, has recently shown his humorous and funny side in film and television dramas and has been loved by the audience. In this film, he plays the role of "Sung-cheol", a mysterious restaurant owner who looks friendly but makes people feel a little scary.
