The kids are so fed up with their Super Hero mums and dads spending more time saving the planet than looking after them that they've formed their own group of heroes - the Super Zeroes Which is very lucky for the citizens of Multiplicity - because the Heroes are currently falling over themselves to welcome a group of inter-planetary visitors The visitors say they've come in peace, but anyone - apart from the Heroes, that is - can see that that's the last thing they've come in It's more like they are in the invasion mode Luckily Ben, Pippa, Marcus, Toby and Jewel are on hand to save the day, save the city, and save their parents' face
