Is it Actually Love for Lexie Byrne (aged 421/4)

Five days before Christmas. Lexie is living in Dublin with her gorgeous new baby, Frances, and Adam is working hard to move his life to Ireland so they can be a family. Then Lexie's mother, Barbara, arrives on her doorstep: she's leaving Lexie's dad and looking for adventure.

What else is a woman to do? Go on a road trip, of course. Lexie and Barbara embark on a journey to Ireland's Wild Atlantic Way, looking for the long-lost daughter of Lexie's late friend Mairead, with plenty of laughs, tears and a broken-down car along the way.

Then it's time to collect Frances and get to Adam's for Christmas Eve. But as usual, drama is waiting for her arrival and forces Lexie to give the worst ultimatum. Will Adam make good on his promise to move to Dublin, or is this Lexie's last Christmas ever with the Coopers?
