This is also referred to as the "Bottom Middle Phone".
You receive a call saying Sonetti received a shipment in and that it is sitting in a vehicle in west Guernsey City. When you get in, however, you realize that the truck was fixed with explosives and must carefully drive it to Vesuvio in northwest Hackenslash. After getting the bomb disarmed, you have to then take it to Seymour Reamer's place in northeast Guernsey City. When you arrive, Seymour refuses to take the truck and now you must take it to Crazy Bob's place in east Hackenslash, in order to teach Seymour a lesson. Once again, the truck becomes armed with explosives and you have to drive it back to Seymour's in northeast Guernsey City. After parking it in his garage and letting it explode, you see Seymour running for it. Simply chase him down and shoot him to end the mission.
