Summary

While Daniel is in England researching Merlin, Landry invites the rest of the team to spend some quality time with him at Jack's cabin.

However, Cam is the only one that gets there, as the rest of SG-1 go off world to investigate a mysterious invisible beast, that has been brutally killing people. The beast is a harmless native animal whose DNA has been altered by a parasite.

Suspecting that the Ori are involved, Sam works out that the incidents are linked to the Sodan cloaking devices that the SG teams have been using. One of those devices is missing, stolen by a Trust operative and a parasite is loose on earth in the woods around the cabin!
