Звездные врата 1 сезон 20 серия (Эпизод 20)

The team arrive on Octasar where a Dr. Carrie Mason of the SGC is working with a local scientist, Dr. Bri'sal, who is working on a project of universal telepathy as part of a scientific conference and believes the Tlak'khan can help him - they're playing him, naturally, since Bri'sal's fellow scientists don't support his project. Stacey overhears them while the rest of the team convinces Mason they're not traitors. Mason doesn't believe them and when the project succeeds the Tlak'khan take control. The team launches an attack but the mind-controlled scientists are forced to attack them, but Mason grabs Da'kyll's device, freeing everyone and forcing the Tlak'khan to retreat.
