Led by the strict and demanding Frank, a group of students train at the Swedish Police Academy to become police officers. After the initial tests remain a diverse class of students: P-O Gren who keep his racist beliefs secret, Larsson the joker, Jesus who has left a criminal background, Ulrika who may or may not be a lesbian, Johan and Eva who become more than friends, Jessica who has a hard time being a single mother and Anna-Karin who wants to become a police to please her father. All of them will gain valuable experiences before graduation.
