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 must Ove be bitter just because he doesn't walk around with a smile plastered to his face all the time?

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.
