Enterprise picks up a distress call from a Vulcan ship, the Seleya, which T'Pol recognizes as a ship she once served on. The ship is located in a somewhat treacherous asteroid field - the asteroids are moving in a chaotic, unpredictable pattern due to the Expanse's spatial anomalies. Archer, Reed, T'Pol and Corporal Hawkins set out for the ship in a shuttlepod and are encouraged when there appear to be bio-signs onboard. Once they board the Seleya, however, it appears eerily deserted. Apparently, the Vulcans were attempting to line the ship with trellium, but didn't get very far. As the team continues to explore the ship, they are surprised by several hugging, zombie-like Vulcans who attack them. The crew manages to fend them off, but the strangely altered Vulcans block them from the airlock, cutting off their escape route to the shuttlepod. What's worse, T'Pol seems to be suffering from the same symptoms as the crew of the Seleya.
