A working-class British man returns to his family in post-war East London after serving in the Second World War, only to find that life at home has changed considerably in his absence. The series follows Harvey Moon as he struggles to readjust to civilian life, rebuild his relationships with his wife and children, and find his footing in a society undergoing rapid social change. Domestic tensions, neighbourhood characters, and the shifting expectations of a new era provide the backdrop for the show's blend of comedy and drama.
