A UAV glider crashes on PJ2-445 against what looks like a giant mushroom; before the camera gives out, a humanoid is seen. SG-1 is sent to retrieve the flight recorder and finds lots of young mushrooms among the dwellings of the humanoids, naked except for white paint, who seem naively friendly but don't speak, so Daniel has to try scribbling or sign language. When several natives faint, the others chant, apparently in vain, and the team calls medical help, fearing to have initiated an epidemic. Even taking one native to the base, Dr. Frazier fails to find their functioning or cure. Fearing to be infected, Jack and Daniel return too; Teal'c has only a short attack, while minding the strange plant as Daniel asked, and precisely it's symbiosis proves crucial...

Sam is testing an Unmaned Aerial Vehicle (UAV) and the drone crashes on a planet. When its camera shows an alien near the UAV, the SG-1 travels to the planet to retrieve the drone. On the arrival, they establish contact with a weird inhabitant and follow him to his village. Soon several inhabitants faint and the SG-1 believe they have brought some pandemic to the natives. They bring one native to the SGC and Dr. Fraiser tries to find a cure. Will the inhabitants be doomed to die?
"One False Step" is one of the weakest episodes of "Stargate SG-1". The forgettable story is annoying and silly and is totally different from the other episodes. My vote is six.
Title (Brazil): "One False Step"
