Grandmother Vanessa Redgrave narrates the tale as Mole Alan Bennett's underground home is crushed when the meadow above is wrecked by a steam shovel driven by Weasels. The Water Rat Michael Palin escorts Mole to meet Mr. Toad Rik Mayall, a flamboyant, impulsive soul who proudly proclaims a love for speed and novelty. Toad instantly embodies a restless energy, inviting the duo to join him in a brand-new horse-drawn caravan and a life on the road. This is the spark that sets the story into motion, as the riverbank friends collide with modern temptations, grand schemes, and the looming threat of the Weasels’ scheming grip on the valley.
Toad’s fascination with motoring soon spirals out of control. He gleefully dives into the world of cars, but his driving is reckless, his finances precarious, and his loyalty questionable. He funds his car habit with loans from the Weasels, and their cunning Chief Weasel Mark Lockyer uses threats and manipulation to force him to surrender control of Toad Hall. The more Toad revs up his passion for engines, the more dangerous and relentless his appetite becomes, pulling his friends into a widening tangle of danger and deception.
An uneasy alliance forms when the trio—Toad, Rat, and Mole—has a tense encounter with the Weasels in the Wild Wood. They retreat to Mr. Badger’s underground home, where Badger Michael Gambon tries to calm the storm and restore some sense of restraint. Badger’s steady, sober approach clashes with Toad’s impulsive thrill-seeking, and the elder creature’s caution weighs heavily as the situation spirals toward catastrophe. The tension reaches a breaking point when Toad’s devotion to speed leads him to steal a motor-car outside a pub and land him in jail. The courtroom becomes a battleground of wits, with the Chief Weasel cleverly disguising himself as a rabbit and swaying the jury. The Magistrate James Villiers presides, but the trickery works, and Toad erupts in court before the Judge sentences him to a hundred years in a castle dungeon.
Meanwhile, the Weasels seize Toad Hall, evicting Rat and Mole from their beloved home. The friends forge a plan to free Toad by tunneling beneath the castle, a bold and dangerous move driven by loyalty. Their effort is helped by the jailer’s daughter Emma Chambers and her sardonic tea-lady aunt, who provide a crucial human touch in a story filled with animal cunning and mechanical danger. Together they mount Engine No. 592, and the engine driver, sympathetic to their cause, allows them to ride on the footplate as police lurk behind on neighboring carriages.
The chase intensifies as the engine roars toward a tense showdown. The police wave furiously, trying to halt the runaway train, while Toad faces the fear of capture and the consequences of his hubris. A series of close calls and quick reversals culminates in a dramatic derailment, and although Toad escapes the immediate danger, he is soon abducted again by the Weasels.
The true scale of the Weasels’ plan comes into sharp focus: they have built a dog-food factory atop Mole’s home and intend to blow up Toad Hall to make way for a slaughterhouse that would transform Riverbank life into something unrecognizable. Badger and Rat hatch a plan to infiltrate Toad Hall wearing Weasel disguises, only to be discovered. In a gripping sequence, Toad, Badger, and Rat are strapped over the factory’s mincing machine, a grim tableau that tests their courage and resolve. Mole breaks into the rotting heart of the factory and disables the machine, enabling their escape.
In a surprisingly early moment of “victory,” Clarence and Geoffrey, two key Weasels, turn on their Chief in a misguided bid for power, sparking chaos as their factions fight among themselves. This distraction gives the trio a real chance to strike back. They launch a raid on the house, and the Weasels are left scattered and incapacitated. Yet the Chief survives the attempted coup, and a final, desperate chase to stop him from reaching the factory continues. Unbeknownst to both sides, Rat and Mole had earlier swapped the labels on the explosive containers, leading them to believe the detonators lay in bone supplies for the factory rather than the real danger. The Chief, in a last, reckless gambit, triggers the explosion—only to realize too late that the factory itself is the true explosive. The blast destroys the dog-food factory and the Chief with it, and Toad Hall stands intact, its residents alive and safe.
With the dangerous ordeal behind them, Toad delivers a public vow to abandon motor cars and grow more mature, though a sly hint of his restless nature remains. Mole’s home is restored, and life on the river resumes its slower rhythm—yet a new note of mischief lingers. In a final, comic beat, Toad is seen talking to an airplane salesman, a clear wink that his love of novelty has simply found another outlet. He takes to the skies, the crowd reacting with a mix of amusement and exasperation as Badger vows never to aid him again. As the credits roll, Toad’s silhouette sails across the country and out to sea, the river’s tale closing with the promise of more adventures to come.
