In 1919, Frank Gibbons returns home from army duty and moves into a middle-class row house, bringing with him wife Ethel, carping mother-in-law Mrs. Flint, sister-in-law Sylvia and three children. Years pass, with the daily routine of family infighting and reconciliation occasionally broken by a strike or a festival.
Unfortunately the movie This Happy Breed is not yet available on HBO Max.
