To get a job in a female trio, Per Fagernæs dresses up in women's clothing and calls himself Martha. Together with his "boyfriend" Poul, the four of them travel to the countryside. Martha immediately gets an admirer, which she is not particularly happy about. Martha is drawn into the women's movement by the mayor's wife, and at a women's rights meeting she is nominated as a candidate for parliament. Later, she is elected, beating the mayor of the town by one vote. Meanwhile, both Martha and Poul are having problems with love, as they have both fallen in love with two real women from the trio. But how do you declare your love when you are engaged to Martha, and how do you get rid of Martha?
