Vinnie assignment is to infiltrate Organized Crime, so he is sent to a prison for 18 months, and everyone thinks he is a criminal including his mother whioh ticks him off. His boss is Frank McPike and the Lifeguard is his link to him and his counsellor if he ever needs one. After three seasons, Ken Wahl left the show, so Mike Santana, the U.S. Attorney who helped send Vinnie to prison for his cover, was tapped to replace him. Not long after helping Vince, he made a mistake and would be disbarred. Three years later, vince was investigating something and called Mike for help, and later Vince disappeared, so Frank tried to find him and the last thing he did was talk to Mike, so Frank went off to see him. They would not find him and Frank asked Mike to join the OCB.
