A well respected lady, in a small Cornish fishing village, faces terrible financial troubles after her husband's suicide leaves her with nothing, bar huge debts that she can't pay off. He has e-mortagaged everything she thought they owned and the bank are ready to foreclose on the whole estate.
Faced with this atrocious state of affairs and facing the fact that she has no working experience, except her gift at rearing plants, Grace Trevethyn (Brenda Blethyn) struggles endlessly to save her much loved home.
Meanwhile, her gardener Matthew (Craig Fergusen), is struggling to make a few marijuana plants successful whilst hidden under a bush in the local cemetery.
With the knowledge of Grace's impending doom, and her genius with plants he decides to ask her to use her greenhouse to grow his plants, sell them and make some money.
He is wanting to get married, but needs capital. What he doesn't know is that his girl friend Nicky (Valerie Edmond) is pregnant and thus fears that they will be busted for growing marijuana.
While supposedly working, the whole village including the local constable is well aware of the endeavour and is praying for their success.
When the plants come in, Grace takes the crop to London and tries to sell it to a ruthless, but charming drug dealer called Jacques Chevalier (Thcheky Karyo). This is the starting point for everything busting out.
A truly entertaining and highly hilarious film - true genius!
