From the introduction: Wrench is back on the job, but there is another crisis that threatens the survival of Hamilton. The town's power source has failed, causing water shortages and threatening the crops that the town depends on for survival. Wrench can fix the power supply – but he needs a special and rare part to do so. Thankfully, Wrench has a contact that can supply such a rare part. The party will need to escort Wrench to the city of Las Vegas to meet with his contact and retrieve the part.
