David and Goliath FC is a youth soccer team run by a small church. For the team's ace, Dong-chan, soccer is not just a hobby, but his entire life. Fueled by a burning passion for victory, Dong-chan doesn't hesitate to engage in rough tackles and dangerous plays. Every time Dong-chan dominates the field, the referee's whistle blows incessantly, and opposing players fall one by one due to injuries. Unable to watch this any longer, the team captain, Jeong-hwan, decides to take action.
