Season 5
SG-1 trains a team of raw cadets, and Colonel O'Neill is forced to take them into a real-life battle situation when he learns of a possible alien incursion at the S.G.C. After an accident with the Stargate traps Teal'c in transit, SG-1 must turn to Russia – and to their enemies – for help before time runs out.
