When Sarah becomes concerned that no one will save the world when she and the gang are not there, Mr Smith proposes creating a set of ĎAlien Filesí, cataloguing all the extraterrestrial menaces they have faced.
File #6: Luke returns home from university, only to discover that Sarah, Clyde and Rani have gone to the Pharos Institute to examine a fossilised Silurian egg. With nothing else to do, Luke helps Mr Smith fill some gaps in the Alien Files, recounting his encounters with the Judoon, Androvax and Mr Dread.
