Enzo Biagi - La lunga marcia

Two middle-aged bachelors use the same apartment for their romantic meetings.

Gabriella, a maid, wears a jewel at a dancing party which belongs to her mistress, and when it is stolen she is accused of the theft and sent to jail. Some other maids organize a search party for the real thief who seems to be a moustached youth who continually sings a popular song.

In the summer, while their wives and children are away, four men try to enjoy their free time.

This is a very light comedy involving multiple love triangles (or really more complicated geometries) of confused, mismatched, or ambivalent lovers. The script includes witty dialogue and humorous situations; most of all on display is the ridiculousness of the human compulsion to pair up.
