Erica Thomas and Claire Mason are very much in love. They have a new home, a boisterous three-year-old and with Christmas coming, it's going to be a joyous time of year. But Claire wants more than that. Claire wants to invite their parents over, she wants a big family Christmas, filled with holiday cheer and lots of love. But as Claire's mother interferes and begins handing out invites to all and sundry, Erica finds herself having to deal with argumentative family members, a neighbour she's convinced is trying to steal her girl and one disaster after the other. Suddenly Christmas is looking far from joyous.
