 While surveying an uninhabited planet, Enterprise is met by a Tellarite ship. Captain Archer is abducted by Skalaar, a Tellarite hoping to collect a bounty placed on Archer by the Klingons. Meanwhile, a microbe from the planet infects T Pol and Phlox. The affliction causes T Pol to prematurely enter Pon farr, a chemical imbalance invoking Vulcans urge to mate. Phlox tries to treat an emotionally stable T Pol, who is getting too close for Denobulan comfort.
