A piano player meets and falls in love with a beautiful and voluptuous woman who, by some strange procedure, leaves the man unable to move but with a permanent priapism. After some time he becomes sick of it and she relieves his paralysis. Eventually she gets bored and decides to leave, but he can't take it because he loves her…

In this stylish and offbeat black comedy, Benito ( Jerry Calà) keeps a diary of his sexual fantasies and cravings. As a result of his on-again, off-again relationship with the beautiful and insatiable Luigia (Sabrina Ferilli), his thoughts along these lines have grown increasingly bizarre. For his own part, he is driven to pick up and bed women at almost every opportunity. As the fantasies recorded in his diary consume more and more of his life, and grow darker and darker, his ordinary waking life becomes flatter and duller, until he disappears altogether.
