Ove is the quintessential angry old man next door. An isolated retiree with strict principles and a short fuse, who spends his days enforcing housing association rules that only he cares about, and visiting his wife's grave, Ove has given up on life. Enter a boisterous young family next door who accidentally flattens Ove's mailbox while moving in and earning his special brand of ire. Yet from this inauspicious beginning an unlikely friendship forms and we come to understand Ove's past happiness and heartbreaks.
