Set in the 24th century, the series follows the adventures of the Starfleet and Maquis crew of the starship USS Voyager after they were stranded in the Delta Quadrant far from the rest of the Federation.
In these episodes, the Federation starship Voyager makes a "pact with the devil" (i.e. the Borg) in order to combat a new enemy which poses a serious threat to both.
The territory covers thousands of star systems and is too big to go around, but they find a narrow path through the sector that the Borg avoid likely due to the numerous gravimetric distortions within it.
Eventually Voyager reaches the Northwest Passage, only to find a fleet of bioships waiting, with more emerging from a quantum singularity.
Janeway proposes a temporary alliance with the Borg to face a common threat, offering the Doctor's cure for the Species 8472's infection as a bargaining chip.
The Borg accept Janeway's offer of the modified nanoprobes in exchange for safe passage through their space, and she and Tuvok begin discussions.
Janeway stops them by suggesting they choose a representative Borg for her to speak through, citing that they did this once before when they turned Captain Picard into Locutus.
The Borg transport Janeway, Tuvok, Seven, and several drones to one of Voyager's cargo bays before ramming the bioship with the cube, destroying both of them.
Seven learns from the Collective that Species 8472 have killed millions of Borg and several planets in the middle of their territory, and demands Chakotay direct Voyager to help.
She has Chakotay placed in the brig for disobeying orders (but really to appease Seven) and continues work on the weapon, as several bioships are detected heading towards them.
They quickly reapply their modifications to a large-scale weapon that destroys most of the enemy fleet and forces the rest to flee with Species 8472 retreating to their realm en masse, ending the war.
The crew have prepared for this — Chakotay uses a neural relay to distract Seven long enough for Torres to electrify the console, knocking Seven out and breaking her connection to the Collective.
The review in Entertainment Weekly praised Kate Mulgrew's performance in the first part of "Scorpion", saying that the "quietly desperate" character "adds a vitally important emotional core to the ensuing star wars".
