Once in a Lifetime (2000)

Synopsis by theflixtor - Mona Bergström is a sweet eurovision-obsessed woman in her 30s. She is married to a lazy husband and has four children, all named after her favorite Swedish Eurovision popstars. Her brother is a crossdressing guy self-titled "Candy Darling". Mona works in a retirement home for disabled people, where she is responsible for taking care of a young man named David who suffers a movement-restricting disease forcing him into a wheelchair. David's parents have abandoned him, as they wanted a normal child. Mona holds a big place in David's heart, and vica versa. David's goal is to get his parents to come and visit him, and he wants to show them that he is a great person, despite his handicap. Therefore he works with music on his computer, and his goal is to create a song, send it to "The Cardigans", a famous Swedish band and have them play the song and credit him, hoping his parents would spot it and want to visit him.
