When SGC detects an alien craft approaching the Earth, they determine it's likely that Martin Lloyd's old friends are up to something. For his part, Martin is now a creative consultant on a science fiction television show called "Wormhole X-Treme!" which, in a very hammy way, is similar to the exploits of SG-1. The Pentagon is happy to let the show go on and Col. O'Neill is named as a technical advisor to the programme to find out what Martin knows. It turns out that Martin has again had his memory wiped and in fact knows nothing. When Sam and Daniel check out his house, they find that he is under surveillance and that NID is somehow involved.
