It's the story of five unlikely allies in life, teaming up and buying a house. It's a grand social experiment with one glaring problem: they'll have to actually live with each other.

As Ben, Ainsley, Harry and Liz kick off their housewarming celebrations, Heather doses herself up on a concoction to combat her urge to return home. Will she last the night or farewell this new life?

Living arrangement boundaries have been pushed just a little too far. Nudie strolls, hygiene complaints and a general lack of self awareness see everyone, bar Ainslie, ready to kick Ben out.

Ainsley, Heather, Ben, Liz and Harry have decided to sell. The drunken joke turned reality is officially coming to an end. As the auction nears it's crescendo, where will the housemates be left standing.
