Filip works as a coat janitor at a restaurant; he is a dreamer who has failed in life and sees people as the clothes he has in his wardrobe. On one night, three guests enter the restaurant: the extensive Viding with his beautiful wife Jane, and the remorseless manager Kurtz. Viding, who owes Kurtz money, demands Jane be accommodating toward him. Filip watches as she pulls a gun.

When silly inventor Svensson gets mistaken for Swedish/American aviator Smith, he is accidentally enlisted in the military and drawn into unexpected romantic affairs.

New explosives will be demonstrated for the military authorities, but some shady characters looking to steal it to sell it to a foreign power.
