The episode is almost entirely a flashback that Colonel Foster has as he sees a woman while dining with Colonel Alec Freeman:

Unexplained communication blackouts are affecting the SHADO Moonbase. Foster believes that the nearby Dalotek Corporation lunar base may be causing the issues through use of their geological scanner. During another blackout a Lunar module crashes when trying to land, killing the crew on board.

Foster investigates Dalotek and disables a piece of their equipment thought to be the cause. However, this does not stop the blackouts. The Dalotek team discovers an alien jamming device, placed by the aliens in a lunar crater using a meteor that crashed on the Moon (a fact that Commander Straker realises while watching a TV interview with Dr. Frank Stranges). Foster sends out a team to destroy the jamming device before an incoming alien UFO attacks Moonbase. With the device destroyed, the UFO can be targeted and also destroyed.

The epilogue reveals that the woman was Jane Carson, the Dalotek employee Foster was flirting with, who had her memory wiped due to SHADO security protocol[4].
