Withnail And I portrays the last throes of an eccentric friendship during the final days of the sixties. Withnail and I are two young would-be actors who wake up one morning to find only ninety days left in the decade.
Bound together by poverty and dreams of stardom, they share a flat of indescribable squalor and live on a diet of booze, pills and weed. The two friends decide to spend a soul-cleansing weekend in the country in a primitive cottage borrowed from Withnail's eccentric Uncle Monty.
From the very start things go wrong and their dreams of an idyllic retreat rapidly degenerate into an hilarious nightmare.
