Earth: Final Conflict is a science fiction television series based on ideas developed by Gene Roddenberry.

Early in the 21st century, a race of aliens, the Taelons (often referred to as "the Companions"), travel to Earth and take up residence in limited numbers.

After the cancellation of Star Trek in 1969, its creator Gene Roddenberry began working on other projects, producing scripts and pilot episodes that were shown to various networks, including Genesis II and The Questor Tapes.

20th Century Fox Television expressed interest in producing a pilot episode for the series, but Roddenberry's busy schedule prevented it.

In fact, the only character to appear as a regular during all five seasons was FBI Agent Ronald Sandoval (Von Flores), one of the show's antagonists.

He accepts Da'an's offer to become a Protector, and receives a Cyber-Viral Implant (CVI) that gives him enhanced mental abilities – including perfect recall.

While most CVIs alter the minds of their hosts so they become singularly loyal to the Taelons above all others, including friends, family, and the human race as a whole, the Resistance sees to it that Boone receives a modified CVI that leaves his loyalties the way they were.

Boone continues to search for the true motives of the Taelons and actually becomes good friends with Da'an, a spiritual and very charismatic being who seems to personally hold humans in high regard.

White supremacists steal a sample of the virus and unleash it in a housing center, affecting the entire surrounding area.

The fiancé of the resistance scientist killed by the previously mentioned probe becomes determined to find a way to get his love back.

Augur's experiments accidentally sever Da’an's connection to the Commonality, causing him to revert to a primitive state the Taelons call an Atavus.

Zo’or tries to destroy the Liberation by manipulating human brain waves, but a lucky trip through a time-portal gives Liam the hints he needs to prevent it.

The Resistance finds out that the CVI's motivational imperative wears off after a time, leaving the protectors restored to their own wills.

Liam senses that the CVI of his mother, long-serving Protector Siobhan Beckett, has malfunctioned and attempts to locate her.

Though Doors proceeds to do work separately from the Resistance, Renee and Liam find their interests frequently overlapping, and occasionally assist each other.

The alien planet turns out to be the homeworld of the Jaridians, and Lili is tricked into delivering Taelon Inter-Dimensional (ID) travel technology to their leaders.

After the illusion ends, she realizes that she is in fact, on Jaridia, and is horrified once she figures out that the ID drives she unwittingly gave her new captors, are exactly what they needed to invade Earth.

Time passes back on Earth, during which it is revealed that Zo'or is Da'an's child, Jonathan Doors dies saving his son, and Renee continues to work with Liam.

Lili eventually leaves Jaridia, bound for Earth, with a Jaridian named Vorjack, whose half-human, half-Jaridian child she is carrying.

She proves savvy and intelligent, eventually revealing that she has the rare ability to think and calculate in multiple dimensions, which makes her a target for the increasingly desperate Taelons.

The Resistance goes above ground once again when Renee and Liam team up with an international group, the Atlantic National Alliance, dedicated to defending human interests against the Taelons.

Liam and Renee discover a regeneration chamber hidden deep in a volcano, set in place long ago by Ma'el.

Liam convinces the Jaridians to attempt a "joining" with the Taelons, which, it is believed, will return them to an earlier evolutionary form that is better suited to survival.

Renee and Street are the only ones who know the truth of what's happening: the Resistance is disbanded and the human governments are in no rush to accept the beginning of another war with an alien race.

To make matters worse, Sandoval, left in control of the Taelon mothership, allies with the Atavus leaders Howlyn and Juda.

As the season progresses, a few familiar faces re-enter the fight: William Boone is brought back as a trap for Renee, but he quickly joins her side.

In response, Sandoval and Howlyn revive Zo'or, giving him a new body as a female Atavus, but Renee and Boone are able to defeat their nemesis once and for all.

Final Conflict comes to a head when Liam returns to help Renee stop Howlyn from unleashing his elite warriors from the long-buried Atavus mothership.

At the end of the series, Liam, Renee and Raj'el depart in the Taelon mothership, resolving to bring the few trustworthy Atavus home and indulge in a little adventure along the way.

The series was first shown on CTV in 1997 and ran for two seasons until the network decided to cancel it due to low ratings.
