Waking Ned Divine (1998) meets Up in Smoke (1978) in this wacky British comedy about growing marijuana. Grace Trevethan (Brenda Blethyn is a cheerful upper-class housewife and gardening enthusiast who is blithefully unaware of business matters. This all changes when she learns that her husband fell from an airplane without a parachute. Her husband's numerous hare-brained schemes at getting rich quick left their accounts in utter ruin. Worse, if she does not raise 300,000 pounds quickly, she might lose her manor. Out of sheer desperation, she turns to her oddball Scottish gardener Matthew (Craig Ferguson), who suggests growing pot. Grace puts her green thumb to work, and in the blink of an eye the greenhouse is converted into the biggest marijuana farm in Cornwall. Soon, word gets out to the not unsympathetic townspeople, including the local doctor -- who is somewhat of a pot enthusiast -- and a horror flick-loving Vicar. Unfortunately, a nervy French drug lord (Tcheky Karyo) also learns of their scheme and soon starts causing trouble.
