Our brave men venture down river on Captain Jim’s boat. Except it’s more like a rusty raft. And by venture down, I mean get flung downriver.
Despite Jim’s reassurances, many of the passengers feel uneasy, and his skills don’t impress anyone not naive enough to think he’s just playing around.
Eventually, the boat comes to its final resting place, a bank of a river in the middle of nowhere, in the middle of Hell’s Canyon.
