Lejontämjaren (The Lion Tamer) is a Swedish film which was released to cinemas in Sweden on 7 February 2003,[1] directed by Manne Lindwall.
One night Simon sees a naked man with briefs on his head and hears his mother's laugh in the background.
In school during the lunch time he tells his mate Tove about his mother and the "briefs-man" whose real name is Björn.
The other boys laugh but Tove is angry and throws her milk on "Kobran"'s face and she and Simon escapes into the headmaster's room.
First Alex is nice but later he is angry and attacks Simon and forces him to fix that it won't be any "relationship" between Björn and Karin.
The next day Simon and Tove write a letter where they pretend that Karin wants to revoke the relationship with Björn, and Simon puts it in Björn's pocket when they meet, but Karin denies that she wrote it.
Simon tells Alex that he can't hate his mother for life and together they go to Anna's home.
When they're back, Alex doesn't want to tell that they met his mother but Simon says that if they do it together it'll be fine.
