"Rudy" is adapted from the true story of Daniel Rudy. Rudy (Sean Astin)'s family is very passionate about football games and is also a loyal supporter of the Notre Dame University team. Rudy, who wanted to go to Notre Dame University after graduating from high school, gave up because of poor grades and went to work in a steel plant after graduation. On his 22nd birthday, his friend gave him a coat with the words Notre Dame University printed on it and encouraged him to realize his dream. The accidental death of his friend in the steel plant hit Rudy hard. He left his girlfriend who was already talking about marriage and boarded the train to Notre Dame University. After entering the university, he studied and exercised very hard. With his tenacious fighting spirit, he was selected by the coach to join the substitute camp of the school team, but he never had the opportunity to play. Finally, he came on as a substitute at the critical moment of an important game and helped the team win the game. The parents and family members who appeared at the scene were also very excited. After 1975, no one from the Notre Dame University team was lifted on the spot. In 1976, Rudy graduated from Notre Dame University, and his five younger brothers also went to college and graduated successfully.
