Federico Fellini welcomes us into his world of film making with a mockumentary about his life in film, as a Japanese film crew follows him around.

Although the drug is present in this film, the Crack this movie is about is, metaphorically, the crack in society which all the protagonists inhabit in a rundown neighborhood in Rome.

Valentine Demy stars as Eva, the gorgeous queen of the town brothel, which she left after inheriting a villa from a wealthy client. Now alone and bored, she picks up three handsome young men (including David D'Ingeo) and, one after the other installs them in her villa where she lovingly cares for each of them. The boys are more than happy to share exuberant Eva's brazen sensuality, without any jealousy, whilst Eva entertains them with arousing tales from her brothel days. However, the idyll ends when Eva falls for an older businessman, upsetting her young lovers who then plot to kill her. But they soon realise instead how Eva has changed their lives for the better, and they happily set off for more adventures leaving Eva the chance to begin a new life.

A young man named Andrea arrives in a small villa and intends to stay in a hotel located on the outskirts. At the reception, a girl, Marta, urges her to stay better in the village, that they are complete. But the traveler insists and gets the room. There you will witness that the inn really works as a luxury brothel to satisfy the sexual whims of wealthy customers. Marta is married to a man older than her, anchored in a wheelchair, who desires Laura, a young lady who loves his wife and is a prostitute of the select clients. Marta embauca to the young woman promising that when they get enough money they will go away together of all that, but Andrea is not there by chance.
