During a visit to the Nasyan planet, under the first goa'uld attack in centuries, a victim's breath given mouth-to-mouth infects Sam, at first unnoticed. Soon her behavior changes, more military and assertive, and she seems to suffer from amnesia. Cassie senses immediately Sam really hosts a goa'uld, which is confirmed by her attempt at gunpoint to escape via the star-gate, and since the aliens now seem able to enter via small skin wounds as in her throat, Dr. Fraser points out there may be others in the base. Sam is jailed but allegedly hosts Jolinar, a 'Tok'ra' or good, anti-warlord goa'uld underground rebel, being chased by an 'ashrak', a goa'uld hit man, who has already started his deadly assignment on earth...

Full of Action Episode
10 June 2015 | by See all my reviews

During a Goa'uld attack to Nasyan planet, Sam is infected while giving mouth to mouth resuscitation to a native. The SG-1 and the survivors goes to the SG-1 and Sam has a strange behavior. After visiting Cassandra, the girl feels that Sam is hosting a Goa'uld and she tells to Jack. Sam is arrested and the Goa'uld claims to be Jolinar, a rebel Tok 'ra, and he does not want to damage Sam. Further, among the survivors from Nasyan, there is a Goa'uld ashrak that is hunting him down. Teal'c believes that the Goa'uld is telling the truth but who might be the hit man?

"In the Line of Duty" is a great episode of Stargate, with a good full of action story. It is strange that Sam uses her mouth in a wounded alien and the writer should have used another way to infect Sam. Now the viewer is aware that there are "good Goa'ulds" and not only the evil ones. Cassie finally returns with a short but important participation. What will be the effect of the Goa'uld in Sam? My vote is eight.
