An incessant granny is kidnapped by two dim-witted crooks and used to hold her wealthy son to ransom. When her son refuses to pay she must forge her own escape and find the reason why.

I don't think the grandmother needs to escape, This should be 'The Ransom of Red Chief' but with an old lady.

In other words, the granny is so annoying that the hapless?kidnappers finally just give her back.

Sounds a bit too much like "Ruthless people" ?(1986), only with a granny instead of a wife. Try and find a way to make it a bit more different from the other film.

Hey, did you edit the original logline, on this page? The oldest comments make no sense.

This film's concept sounds a lot like Ruthless People with Danny DeVitto and Bettie Middler. Check it out and see if it helps.
