"Evolution" was the first episode in the third season of Star Trek: The Next Generation.
The USS Enterprise-D orbits a red giant and some stellar matter. Suddenly, something rocks the Enterprise. Picard quickly orders Wesley Crusher to stabilize, but the ship isn't responding. In engineering, La Forge reports that there is nothing wrong with the inertial dampeners. Back on the bridge, Worf says they are heading straight into the path of the stellar matter. The captain orders shields up but Worf cannot; "the shields will not respond," he shouts, as the ship drifts towards the stellar matter with only thirty seconds until impact.
Picard orders a manual override on the shields while Riker tells La Forge to reset the inertial dampeners. The shields begin to rise but the inertial dampeners are still unresponsive. The chief engineer activates the impulse engines in full reverse, which seems to stabilize the ship, but the momentum is still carrying the Enterprise into the stellar matter. Data reports that all systems are reporting normal. Picard asks the computer what the cause of the control malfunction was but the computer has no record of any such error. Confused, he checks Data's console, but everything appears normal.
Did You Know the final season of Star Trek: Enterprise was shot almost exclusively on Sony 900 digital cameras, thus making it the first Trek series to be photographed on digital video instead of film. The only scene in the entire season that wasn't shot on digital video was the teaser of "In a Mirror, Darkly", which was shot on 35mm film to better intercut with stock footage from the 1996 movie Star Trek: First Contact.
