After all, the precious gem belongs to statuesque Mrs Delimeri, a wealthy Greek socialite, who has insured it for 5,000,000 drachmas. So, to ensure the lady's safety and safeguard her prized possession, Nikitas teams up with Detective X, a seasoned undercover investigator. However, this mission is more challenging than anticipated--every ambitious thief in town is after the jewel. As the situation reaches breaking point, can Nikitas, a kind-hearted guy who wouldn't hurt a fly, save the day?
