Beware of spoilers for these episodes below! Here’s how SCI FI describes the episodes:
As the rest of SG-1 prepares to join Landry (Beau Bridges) and Mitchell (Ben Browder) on a retreat, Teal’c (Christopher Judge), who is assisting the SG-3 team, discovers that the inhabitants of a distant planet are being mutilated by a savage and elusive alien creature. While SG-1 fears the Ori’s sinister work is at play, they soon discover the creatures are being created by a parasite not indigenous to the planet.
Meanwhile, Mitchell and Landry are the object of surveillance while staying at General O’Neill’s cabin. As SG-1 receives word that the creatures are appearing on other planets also, Mitchell discoveres some hunters who have been the victim of a similar attack on Earth. Desperate to find the origin of the parasites, the team makes an alarming discovery: not all planets affected by the attacks were visited by the Ori, but they were all recently visited by SG-1. Horrified to discover that they could somehow be to blame, SG-1 must determine how to stop the creatures before they kill again.
Martin Lloyd (Willie Garson) returns to the S.G.C. looking for assistance from SG-1 with his feature film script. The team is reluctant, especially Lt. Colonel Cameron Mitchell (Ben Browder), who is excited about his next off-world mission which marks the 200th trip through the event horizon. However, when technical glitches prevent the team from gating off-world, they are stuck in the boardroom under the orders of General Landry (Beau Bridges), because the Pentagon believes a successful science fiction film about intergalatic wormhole travel will serve as a good cover story to keep the Stargate Program a secret.
The notes session, however, quickly devolves into the team members pitching their own versions of a successful sci-fi film — including tributes to THE WIZARD OF OZ, STAR TREK, a younger and edgier SG-1, and even a wedding that features the return of General Jack O’Neill (Richard Dean Anderson).
“Uninvited” is expected to air on August 11 as the fifth episode of Season Ten, followed by “200” on August 18.
SCI FI will also air a new behind-the-scenes special, “SCI FI Inside: Stargate SG-1 200” on August 18 at 8 p.m. Eastern/Pacific. The special will be reaired that night at 1 a.m., and again on Friday, August 25 at 6 p.m.
