Each week two families with very different values take part in a two-week challenge in Wife Swap. The wives from these two families exchange husbands, children and wives (but not bedrooms) to discover just what it's like to live another woman's life. It's a mind-blowing experiment that often ends up changing their lives forever.

This time there's a new twist. After the rules change, the wives can call for backup, bringing in a friend or family members to help them enforce the rules and shakes things up even more with their swap family.

Watch 'Wife Swap' on 28th January at 10.pm on travel & living.
