After the starbase is abandoned (except for Archer) life support returns to normal and a massive shield (this is way beyond earth technology) envelopes the station preventing the Enterprise from getting through.
Archer must find out what is going on as mysterious robots appear and disappear, and the station seems to be transforming itself. We learn later that a very small mysterious probe had attached to the station. Archer learns that it is not aliens who are behind this but the intelligence that was controlling the 'Dead Stop' station (see Season 2).
Archer must find a way to destroy the station, and save himself in the process, before the technologically advanced station becomes a threat to the whole sector.
