Sky Trackers - Season 1 Episode 14 Aliens

Nikki, Mike and Maggie see lights in the sky one night. They wonder if it's a UFO. Giles seems to be acting strangely and Maggie thinks Giles might be an alien. Mike and Nikki discover that Giles is interested in UFO's: a friend of Giles disappeared while investigating a UFO sighting. Mike, Nikki and Maggie hide in the back of Giles' vehicle as he goes out one night to investigate the cause of the weird lights. The lights appear and everyone is stunned. Whilst not admitting that there could be visitors from another planet, Giles does concede that "there are more things in heaven and earth than we could ever dream of".
