Deep in the English countryside is an inland marina, home to a group of unlikely characters living on their narrowboats.
Life at Watergrove is carefree until a local land-owner decides he wants to build three luxury houses on the residents vegetable plot.
In an unaccustomed act of decisiveness the boaters decide to form a committee to fight this scourge.
Step forward Judy, a lady of physical substance, fierce determination and jocular disposition, who selflessly elects herself chairwoman.
H.Q. is the local pub and it's here that our ageing boaters raise a creaking battalion.
Judy leads our disparate band into battle, implementing a plan code-named Operation Vegetable - a harebrained scheme of doubtful focus.
The boaters find help from an ageing rock star and a TV Gardening programme. Skirmish follows skirmish until one of the boaters is severely injured and the stakes are raised.
Has the despotic land-owner, a man of few morals, driven by power and greed, finally met his match?
Will the boaters look like toothless turnips or can they cajole wobbly bodies, more suited to tea-drinking than physical endeavour, to mount the barricades?
Or....have the boaters simply lost the plot?
