Synopsis by Hal Erickson
SG-1 races to the planet P3X 451, hoping to deactivate a black hole. Unable to disengage the Stargate, the SG-1 causes a tear in the time-space continuum, with the area's gravity field threatening to slow down the flow of time and destroy the world. This crisis unexpectedly turns into a chance for redemption for O'Neill's (Richard Dean Anderson) disgraced former shipmate Cromwell (Marshall Cromwell).
