Children's entertainment series. Dave Chapman presents an undercover prank adventure, involving mess, mayhem and full-on anarchy in a family's own home! The kids think they are taking part in a programme called Mega Nanny - what they don't know is that Mega Nanny is their dad in disguise.

Dressed in state-of-the-art movie make-up, a silly wig and women's clothes, Undercover Dad must spend two days undetected while completing a series of messy challenges, getting to know his kids better and winning them a pile of prizes.

This week, Dave brings the Nan Van to Gloucester where ex-military, disciplinarian dad Tony Wasley undertakes the most challenging mission of his life. Will his kids Alex, Lydia and Thomas warm to the odd and mysterious Mega Nanny? Or will they realise that it's Dad beneath the rubbery disguise?

More importantly, will Dad agree to break his own boring house rules to win the prizes? Will he see things from his kids' point of view? Be prepared for extreme fun, extreme emotions, extremely close shaves and extreme cream pie action. Show less
