"Breeders" is an uncompromising comedy that explores the lives of Paul (Martin Freeman) and Ally (Daisy Haggard) as they juggle full-time careers, aging parents, a mortgage and the unenviable curveballs of parenting their young children. When Ally's estranged father appears on their doorstep, the family essentially takes on a third child -- but this one comes with baggage and opinions.
