The Big Reunion lifts the lid on the highs and lows of six chart topping groups, reunited after dramatic break-ups.
Atomic Kitten, 5IVE, B*Witched, Liberty X, 911 and Honeyz dominated the UK music scene from the mid-nineties, but how will they react to the demands of a live performance after years away from the spotlight?
The bands have just two weeks of intensive rehearsals before they step back on stage to perform once again in front of thousands of fans.
Catch the tears and tantrums as each band hopes to recapture the magic that once made them household names.
