De dwaze lotgevallen van Sherlock Jones.

Sherlock Jones is a handyman, a nice man who dreams of doing great things. Together with his dog Watson, he becomes involved in the case of the Karthoum diamond. This legendary stone arrives in the Netherlands to be cut and polished. The mafia attempts to steal the diamond during its transport from Schiphol Airport. They ensure that all security measures are checked by the 'renowned' private detective, because they know he will have no idea what is going on. The robbery is a great success. It's a good thing Watson is there too...
