In this charming romantic comedy from 1940, we meet a carefree man named Johnny, a bicycle salesman who initially has no greater concerns in life than enjoying his freedom. Everything changes when he crosses paths with a young and enchanting woman named Carol, who becomes the spark that ignites his heart.
After a chance encounter on one of those lucky days, they both decide to make a deal: to love each other without strings attached and only for a short period of time. However, as the weeks go by, things become complicated when real life begins to intervene in their plans. While Johnny tries to prove that he is more interested in his freedom than in emotional responsibility, Carol, who is more cunning than she seems, starts to fall in love with the spontaneity of the life she shares with him.
Misunderstandings and hilarious situations ensue when an old flame of Johnny's appears, threatening to disrupt the new romance. As the attraction grows, both are forced to confront their true feelings and the inevitable reality of what it means to be in a relationship with someone else. In a world filled with comedic twists and tender moments, Johnny and Carol must decide if they are ready to leave behind their "no strings attached" pact and face what love really has in store for them.
