Fran, Rita, Emma, Pauli and baby Emmett are a typical Irish family, living under one roof with one another with varying levels of success. Fran has become fixated on the idea of building a bunker to protect the family from the upcoming apocalypse after being influenced by a late night television programme. Rita, working mum and housewife, is bewildered by Fran's new hobby, but try as she might she can't quite get him to let the idea go - despite the fact that the Mayan apocalypse was supposed to occur two years ago. Emma is coping (loudly) with her young son after falling pregnant as a teenager. Living at home means she always has the assistance of her family to keep escape-artist Emmett under wraps. Pauli, still at school with his best friend Matt, is learning performing arts and watching girls from afar. The two boys both share dreams of being actors in the future, but for now a smile from gorgeous Becka will do.
