A flash kidnapping, but the ransom demanded is too small. Michele, aesthetic surgeon, has no doubt: this is a joke. Of course he is sure that a child was calling, his son Andrea could not have been really kidnapped. Soon doubts arise: that Andrea was not the first kidnapping in similar circumstances. Already, other children have disappeared and only those who paid the ransom could re-embrace their families. Who has not done that has not seen them anymore. Despite the contrary opinion of his wife he calls the police, determined to set a trap for the kidnappers. Whether they are children is beyond doubt, but who is maneuvering them and why? Are they really casual abductions or they follow a pattern? When the ransom is withdrawn by a young girl they think to be one step away from the solution, they do not realize a chess match with an implacable opponent is just started.
