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.

Dave brings the Nan Van to south London, where busy dad Pat Begbie undertakes the most challenging mission of his life. Will his kids Ellie, Lucie and Pollyanna warm to the ever so odd and very mysterious Mega Nanny? Or will they bust Dad beneath his rubbery disguise? More importantly, will Dad agree to break his boring house rules to win the prizes? And will he finally 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
