On board Shuttlepod One, Trip and Reed are attempting to locate the Enterprise in an asteroid field that Captain Archer was planning to map. Just then, Reed spots something on one of the asteroids - it is an impact crater surrounded by debris from the Enterprise. Trip and Reed assume that the ship has been destroyed. They are now alone, and have ten days' worth of air left. Trip orders Reed to navigate to Echo Three, a subspace amplifier, using the stars for reference as Navigation is down.
On board the Enterprise, Archer asks after the Tesnians and Ensign Hoshi Sato says that Dr. Phlox is rotating the 34 survivors in order to give them all six hours of boron gas a day. Ensign Mayweather reports from the Bridge that their ETA at Tesnia is 20 hours, allowing enough time to return to meet the shuttlepod. Archer and T'Pol use a mini-shuttle to inspect the damage to the ship, and Archer orders work on a new door for Launch Bay 2. Later, T'Pol presents Archer with her analysis of the scans of the Tesnian ship; they were hit by a micro-singularity. The Enterprise was also hit, but the polarized hull plating dispersed their energies. Archer is skeptical.
Meanwhile, Reed records a message for his parents, and Trip is exasperated at Reed's continued log recordings. Later, Reed 'wakes up' in Sickbay, with Trip unconscious on the next bio-bed, but he has been dreaming. The shuttlepod is then rocked by an impact which breaches the hull. They find two small holes at either end of the cabin and seal them. Reed reports that one of the oxygen cylinders was also breached, leaving them with less than two days' worth of air left. Trip tells Reed that they can survive for an extra half-day if they lower the temperature and use the power for the air recyclers.
Later, Reed records more logs and complains that he has never been able to get close to anyone, but he was starting to feel comfortable with the crew of the Enterprise. Later still, the radio picks up a signal - it is Hoshi hailing the shuttlepod from the Enterprise. She transmits new rendezvous coordinates and gives an ETA of two days. Trip says that they only have one day's worth of air left and no way to communicate with the ship. Trip and Reed jettison the engine, which detonates with a large shock wave, to attract Enterprise 's attention. It works. Finally, Reed wakes up in Sickbay, and Archer tells him that they were suffering from hypothermia when the Enterprise picked them up. Reed looks over to Trip's sleeping form and wishes him a goodnight.
