During a visit to the Air Force Academy, Carter makes the acquaintance of Jennifer Hailey, a promising young cadet with a rebellious streak. Carter sees great potential in her, but Jennifer seems determined to sabotage her future with the Air Force. She is fiercely independent, opinionated, and resentful of Carter to whom she is constantly being compared. On the other hand, Hailey is brilliant and Carter eventually decides to show her what she can look forward to if she stays the course - by bringing her through the Stargate. The two of them visit an offworld research base where O'Neill and Teal'c are on security detail, "babysitting" a group of ungrateful scientists. But the seemingly routine mission takes a deadly turn when they are attacked by alien life forms composed of pure energy. Trapped and cut off from the Stargate, SG-1 must make a desperate gamble to reach freedom before it's too late.
