Basically, from watching the trailer, the movie is based on a man named 'Michael Edwards', also known as 'Eddie the Eagle' or 'Eddie Edwards'. His dream was to always compete in the Olympics, but so many people would put him down, saying that he would never get there. One day he decides that if he cannot compete in the Summer Olympics, he would compete in the Winter Olympics. Where he would compete in Skiing. A character in the movie then comes along and helps him, with competing.The day of the competition comes.
(The trailer stopped where he was just about to jump off)
