Anita Karenová (Truda Grosslichtová) becomes the owner of the clothing company Karen that her father has bequeathed her on her 21st birthday. However, she has no experience in running a business and she would like to acquire some on-the-job training beforehand. Thus she avails herself of the report of Pavla Holoubková (Vera Ferbasová), who has applied for a position at the company, and she writes the recommendation herself. Under a new name she is taken on as a copy clerk in the branch under Jirí Hosek's management. Hosek (Vladimír Borský) falls in love with Anita without knowing who she really is.
