Some seriously weird stuff is happening on Planet Earth. Pollution is cleaned up overnight. A sweet smell fills the air. Strange lights are seen in the skies... Could they possibly be UFOs? Have aliens come to fix our world? Only one boy and his dad - and possibly his goldfish - know that the truth is stranger, scarier - and a whole lot smellier... Kidnapped and taken to a super-secret base, Tim discovers the full extent of the alien threat ... and the extraordinary kids fighting it. With the aid of a little huggy alien, and a depressed guard, Tim and his weird new friends take the battle to the aliens. Oh, and that goldfish has a big part to play...!
