Tony Manero doesn't have much going for him during the weekdays. He still lives at home and works as a paint store clerk in his Brooklyn, New York, neighbourhood. But he lives for the weekends, when he and his friends go to the local disco and dance the night away. When a big dance competition is announced, he wrangles the beautiful and talented Stephanie to be his partner. As the two train for the big night, they start to fall for each other as well.
