In this heartfelt and hilarious farce, Brenda Blethyn stars as Grace, a new widow in a small Cornish town who finds that her late husband saddled her with enormous debt. On the advice of her gardener Matthew (Craig Ferguson), Grace clears out her greenhouse orchids and begins growing marijuana to raise the needed cash. Their misadventures cultivating the crop under the noses of the locals-and bringing it to market in London-make for high comedy. Tcheky Karyo, Martin Clunes also star. 95 min.
