The Enterprise stumbles into an area of space containing cloaked mines. When a malfunctioning, active mine attaches itself to a critical area of the ship's hull, Lieutenant Reed dons an EV suit and attempts to disarm it. Complications arise when the mine's leg penetrates Reed's leg, pinning him to the hull. Captian Archer must find a way to get rid of the mine and save Reed before the Romulans run out of patience.
