Prince Hilarion has been waiting for this day for twenty years. He is about to meet the girl to whom he was betrothed, as a baby. Unfortunately, this girl — Princess Ida — has decided that she does not want to honor the commitment, and has, instead, gone off and started a women’s college. In an attempt to woo her, Hilarion, dresses up as a maiden and sneaks into the women’s compound, accompanied by his friends, Cyril and Florian, who are forced to dress up, as well. Once the “maidens” are in the compound, various girls attending the college discover their secret. These girls attempt to keep their knowledge from Ida, but eventually, she Ida discovers and apprehends the intruders. It looks like violence is sure to erupt, but Ida finally relinquishes and agrees to marry Hilarion.
