Chronicle about how a song came about. Three young people and an orchestra leader visit restaurants and reviews where music, dance and song numbers are performed by Evert Taube, Ulla Billquist, Gustav Wally, and Britt Nilsson.
The tailor Tosse is ordered to return to his old regiment to practice what he learned many years ago. But he asks his assistant Loffe to go there instead of himself. Everything is fine until Loffe gets the same order - at the same regiment. When Tosse comes to the regiment, it becomes a case of mistaken identity. Due to the confusion, Loffe is now Tosse's platoon commander. Plot by Mattias Thuresson.
