Regeneration

The remnants of an alien ship and two frozen cybernetic bodies are uncovered in the arctic by a research team. These aliens soon thaw out and flee Earth, taking the research team with them. Starfleet orders Enterprise to find them, but the crew aren’t prepared for just how dangerous these aliens really are.

Cease Fire

Both the Vulcans and the Andorians make a claim to a small planet and military conflict soon erupts. As the fighting goes on, the Vulcans announce they are willing to discuss cease fire terms. However, Imperial Guard officer Shran believes only Captain Archer can be trusted to mediate the situation, which drags the Enterprise crew into the tense situation.

Rajiin

The NX-01 gets closer to a showdown with the Xindi when Captain Archer takes on an enigmatic passenger: a beautiful slave named Rajiin.

Terra Nova

The Enterprise crew alters course to investigate the mystery of Terra Nova, a legendary Earth colony whose inhabitants mysteriously disappeared decades ago. But when they arrive, they confront descendents of the colonists who have become more alien than Archer could ever have imagined.

Sleeping Dogs

While investigating a gas giant, Enterprise comes across a damaged vessel hovering in the atmosphere, and T’Pol, Hoshi and Malcolm board the vessel to investigate. However, once aboard, they are ambushed by a hostile female Klingon who hijacks their shuttlepod and strands them on the Klingon ship, which threatens to implode under the pressure of the planet’s atmosphere.

The Aenar

Archer visits Shran’s icy homeworld to find an Andorian subspecies called the Aenar, to determine their connection to the marauder destroying ships in the region.

Precious Cargo

Trip boards an alien cargo vessel to help repair a stasis pod, which holds a beautiful woman in suspended animation. When the woman accidentally wakes up, she reveals she’s not a passenger, but a prisoner.

North Star

When a settlement of humans living a 19th-century Western lifestyle is discovered on a Delphic Expanse planet, Archer and crew set out to learn how they got there.

A Night in Sickbay

Archer spends a night in sickbay with Dr. Phlox after Porthos contracts a deadly virus on the Kreetassan homeworld. Crew members suspect Archer’s increased stress level is due to Porthos’ illness, but Dr. Phlox suspects it has to do with Archer’s repressed sexual tension.

Shadows of P'Jem

Archer and the crew are disappointed to discover that T’Pol has been ordered by the Vulcan High Command to leave Enterprise–and equally frustrated at her seeming indifference to leaving their ranks. T’Pol’s last mission as a Starfleet officer, however, proves eventful when she and Archer are kidnapped by a militant faction on an alien planet.

Home

Once the NX-01 finally returns to Earth, the weary crewmen face repercussions of their journeys, both positive and negative.
