Ricardo Diaz

Diaz's final job: stop a French smuggling crew with a Squalo speedboat, then return for the deal as gunfire breaks out — kicking Tommy and Lance out of Diaz's orbit for good.
**Supply & Demand **is the final mission in given to protagonist Tommy Vercetti by drug baron Ricardo Diaz from his mansion in Starfish Island, Vice City.
Some freelancer moors his yacht into Vice City every month. The yacht is referred to as "The Drugboat", since the freelancer sells drugs from that boat. However, he only sells his cargo to the first customers to arrive in his yacht, and Diaz wants Tommy and Lance Vance to be those first buyers.
Tommy gets to the Squalo and meets up with Lance, and the duo decide to get to the drug boat first before other boats make it. Once arriving at the boat, Lance takes control of the Squalo and Tommy begins to protect him and the boat. He fights with the attacking rivals and gets back to Diaz.
