Sorry, we have not watched this yet.
A woman comes out of a laundry holding her cyanotic son in her arms: at the hospital it is discovered that the child had swallowed a diamond. Meanwhile, the body of a woman is found in a car, who turns out to be a widow looking for a man who had disappointed her in love and had asked her to borrow money. The investigations proceed on the double trail of the widow and the diamonds.
