At the end of World War II, the three Fox-Talbot sons and their father the General return to Hartgrove Hall, the family home. It's been in use by the military during the war years, and even before that, the family fortunes were declining. The house is decaying, and they have no money to do necessary repairs. The General thinks the only sensible course is to dynamite the house, and sell the property. The two older sons, Jack and George, war veterans themselves, are determined to save it, farming the land themselves and earning the money to repair it. Harry, the youngest, just eighteen, wants to pursue a career as a composer, but he can't say no to his brothers, and agrees to stay on and help.
Then Jack brings home his girlfriend, popular wartime singer Edie Rose, and Harry falls in love.
