This mission is given by Tam Brodie.
"Jimmy! It's Tam Brodie. Listen - I got two hundred crates of hooky beer sitting in my basement that I can't shift for love nor money. Why? Because the Chinese are flooding the city with cheap chinky booze. I've got bills to pay, you get me? They store the drink down at the dock. Find the booze and destroy it."
From the start, drive to the docks in South Millville where you will find three shipments guarded by six Triads. Kill them, and then destroy the shipments by either shooting the crates or simply smashing them with your car. Once you're done drive to the safe zone to end the mission.
