Saving Grace opens by showing viewers the posh environs in which Blethyn’s Grace character calls home. She’s encountered a bit of a problem, though. Her husband’s died. And in the world of faux-aristocratic English, women, apparently, aren’t prepared to do any sort of work. So, Grace’s pretty well screwed when her husband’s demise reveals a rash of poor business decisions and just as many debts. One of those debts, unfortunate for the character, but fulcrum for the film’s plot, is that Grace’s husband mortgaged the house. And now, she owes 300,000 pounds.
Riding lawn mowers are repossessed as is some well crafted furniture, leaving Grace an enormous house without too much inside of it. What she does have, though, is a green thumb. And when her handy man, here played by Ferguson, asks for a bit of help resurrecting a sickly pot plant, all involved figure they can simply grow a shitton of weed and solve everyone’s financial problems.
The Feguson character seems pleased initially, but his live in girlfriend, whose pregnant, but has told her other half yet, feels the whole thing’s irresponsible. It is, but Grace genuinely believes it to be the best way out of her troubles. Of course, since no one involved has any sort of background in large scale drug dealing, the hapless pair run into a few problems – like the mob, the law and their neighbors, who find it hard not to notice something like a greenhouse full of weed.
As a side, though, the math doesn’t work out exactly. To take care of Grace’s mortgage and make it financially viable to pay her handyman anything, the pair’d need something like a thousand plants. And while Grace’s green house looks pretty packed, there’s pretty much no way that any of this would work. Maybe Ferguson was stoned when he wrote the script.
