The path to parenthood isn't always straight. Andrea and her wife Caroline have it all: great jobs, a loving relationship and a new home. There's just one thing missing: a baby. Amidst the drink-sodden traditions of a family Christmas, they have an idea: if nature can't give them a child that shares both their genes, perhaps Andrea's under-achieving brother Jimmy can? When he and his girlfriend Sharon agree, the four are forced closer than any family expects to be. Will this be the perfect solution? Or a recipe for disaster? This hilarious new comedy offers a fresh take on family, tradition and procreation, questioning not only why we have children, but how.
