From the director of the better known "Alla Ricerca del Piacere" (aka "Amuck!") comes this stylish thriller that involves not only a confusing web of love affairs and relationships, but also - towards the climax - a bundle of twists that are guaranteed to surprise every viewer without becoming implausible at any moment.
And this is the big plus of this movie: The twists all work. The first half moves on relatively slow (similar to Silvio Amadio's above mentioned earlier Giallo), but the viewer already gets enough information to know that the plot isn't as simple as it seems. In the second half the film becomes a roller coaster ride of red herrings, plot twists and other surprises, which makes it decisively superior to Amadio's earlier effort.
The acting is also thoroughly convincing, which is especially important once the film is finished and the viewer gets the whole story. But the most remarkable thing in this intriguing Giallo is the lush, ear-catching main theme that will never let one go after being heard for the first time.
