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.
