Will and Sonny get stuck in Gainesville, Georgia, with a load of chicken feed when the Chicken Growers Co-op is threatened with a quarantine by the government. Will is bitten by a snake while he is working on the rig.
Against Will's objections, Sonny rents the rig to a broker and almost loses it, and more, to a crew that broke in to an armory. To keep them in the dark and out of his way, the broker treats Will and Sonny to a few days at an exclusive resort.
While in New Orleans for the funeral of Sonny's Navy pal, Sonny and Will use the Kenworth as the hearse, and a local numbers runner puts a "package" in the truck. They take the deceased buddy's little girl to Pensacola, Florida, unaware that hoods are chasing them to get the package back.
Will and Sonny go to Bayou la Batre, Alabama to visit Jack, a shrimper buddy of Sonny's. But Jack isn't shrimping; he thinks he has found a sunken ship (from 1864) in Mobile Bay with a $1,000,000 fleet payroll on it.
