Sam (Mafia)

Sam is the tritagonist-turned-final antagonist and the final boss of Mafia: The City of Lost Heaven. He is the best friend of the game's protagonist and playable character Tommy Angelo, as well as Paulie and they feature in several missions together.

History
At the beginning of the game, set in 1930, he and friend Paulie after being chased down by rival gangsters under Don Morello. They come across taxi driver Tommy Angelo after they crash their car, and force him to escape from the gangsters. After succeeding, Tommy drops off the two men at a bar owned by their boss Ennio Salieri and Sam pays him for the damage for the car, and tells Tommy that if he needs anything, to come to them. However in Tommy's mind he isn't interested as he doesn't want to be sucked into a life of crime, but that was soon to change.

The next day Tommy is tracked down and chased by Morello's men for helping their rivals. In desperation he heads to Salieri's bar for assistance, and the two thugs after him are killed and disposed off. After being fired from the taxi company for being afflicted with criminals, and with nowhere else to turn, Tommy changes his mind and is welcomed into the family. Their first big job together was heading out to a bar in the countryside to collect protection money, but everything went sour when Sam and Paulie were injured. However Tommy managed to kill all the thieves betraying them.

A few year later Sam heads out to the country along with some of Salieri's men to pick up a whiskey shipment, however they end up being attacked and Sam is captured. Tommy rescues Sam, and he is brought to a doctor and treated.

In 1939 they are sent to steal a shipment of cigars. Before doing this Paulie proposes that they should rob a bank and make some money on the side. Feeling loyal to the family however, Sam turns down the offer and so does Tommy, which leads to Paulie accepting it and telling them to forget about it.

However when Tommy and Paulie discover that the shipment was hiding diamonds which Salieri refused to tell them about, they decided to rob a bank without Sam's assistance. But when it was discovered they were responsible, Paulie was killed (which was hinted to be by Sam) and Sam lured Tommy to a museum with the promise of helping him. But Sam betrayed Tommy and had his guys waiting to kill him. Tommy shot through Sam's men, and the pair faced off in a gun battle. Sam was injured in the gunfire, and attempted to escape but was shot by Tommy. In his final moments, Sam told Tommy that he will never be able to hide from Salieri's men and one day they will get him. Tommy then shoots Sam multiple times, finally killing him.
