On a seemingly ordinary evening, J, Harris, and George decide that a boat trip up the Thames is just the thing they need to make them snap out of their troublesome state. Though they set off with much enthusiasm, the three men could have hardly predicted the troubles that would follow them on this jaunt. From tow ropes that have a mind of their own to weather that is unbelievably unreliable; from pineapple tin cans that refuse to open to the mysterious disappearance of Harris, this is classic British humor with its timelessness and endurability.
