Winston Nesbitt is a 40-year-old loser. His bosses abuse him, his parents have deserted him, and he loves a co-worker who isn’t aware of his feelings. Just when Winston thinks things could get no worse, his grandmother comes to visit. The problem with that is, she died when he was 24, and she’s now back as a 12-inch tall mischievous spirit determined to make amends for things she didn’t do while alive. And now, there’s nothing she won’t do.
