 Enterprise answers an automated distress call of the Vulcan ship Seleya, lost in the Expanse 9 months ago. Captain Archer, T Pol, Lt. Reed and Cpl. Hawkins dock Shuttlepod One with Seleya, only to be attacked by the survivors. The Vulcan crew have been reduced to zombie-like drones, permanently brain-damaged by a neurotoxin in the Trellium. Meanwhile, Enterprise navigates an unpredictable asteroid field rich in Trellium, an ore that can be refined to make a vital insulation for traveling the expanse with minimal damage from the anomalies. Tucker and Mayweather land Shuttlepod Two on an asteroid to mine the ore.
