James "Jimmy" Cacuzza is the boss of the Cacuzza Crime Family. He and his gang buy weapons from SAMCRO. When one of the weapon shipments was late, the Sons of Anarchy hijacked a truck and gave the contents to the Mafia as a goodwill gesture.
Jimmy meets with Jax Teller to sell him the gun business. Galen O'Shay shows up with Connor Malone and a few others and allows him to test out the guns. After he tries the guns out, Henry Lin and other members of the Lin Triad come to take part in the deal, but Galen kills one of them and wounds Henry to show Jimmy that the IRA is the only source for guns. Galen and Jimmy come to terms with each other and Galen leaves. Jax apologizes to Jimmy, but Jimmy tells him not to worry about it stating that "it was never gonna go with the chinks".
