Meet Ove. He's a curmudgeon -- the kind of man who points at people he dislikes as if they were burglars caught outside his bedroom window. He has staunch principles, strict routines, and a short fuse. People call him "the bitter neighbor from hell." But behind the cranky exterior there is a story and a sadness. So when one November morning a chatty young couple with two chatty young daughters move in next door and accidentally flatten Ove's mailbox, it is the lead-in to a comical and heartwarming tale of unkempt cats, unexpected friendship, and the ancient art of backing up a U-Haul. All of which will change one cranky old man and a local residents' association to their very foundations.
