Enterprise navigates into a stellar nursery hoping to make contact with some of the alien vessels detected among the colorful gases and protostars. Finding a transport vessel escorting a group of alien pilgrims to the "Great Plume of Agosoria", a protostar which emits an epic burst of energy every 11 years, Captain Archer decides to caravan with the pilgrimage ship, and invites the group for a social dinner onboard Enterprise. Relations fare well among the starship crew and the pilgrims culminating with Commander Trip Tucker giving a guided tour of the Enterprise engineering bay. As the group listens attentively to Trip's oversimplified explanation of the warp engines, one pilgrim silently slips behind a bulkhead unnoticed. He opens a panel and dislocates his limb in order to disconnect a conduit within - he is a Suliban. After the disguised invader rejoins the group, the entire ship is suddenly rocked by a powerful plasma storm within the stellar nursery. Unsuccessfully attempting to steer clear of the storm, Enterprise is repeatedly hit with plasma lighting, severely damaging the warp manifold and starting a disastrous antimatter cascade traveling towards the reactor. Instead of completely destroying the ship, though, the cascade is suddenly stopped dead at the very console the Suliban tampered with moments before.
Star Trek: Enterprise, a prequel set before the original series, follows the crew of Earth's first warp five starship. Lead by Jonathan Archer and his crew, the series follows their adventures as they explore never before seen parts of the galaxy, setting foot on new worlds and meeting new races, as well as some familiar ones.
