S4, E16: In a military base, Maggie accesses a lab, where she finds a man hooked up to machinery. She swiftly exchanges a computer chip implanted in his skull with one she has brought, but an alarm sounds, and she bolts. She makes it outside, where the other Sliders await her return to slide. When she appears, they all leap into the vortex... and moments later the real Maggie escapes from the base!
