You are introduced to another Race. Defiances supplies are running low. The search continues for the two children and their kidnappers. We discover more about the Votanis Collective. Irisa and Nolan escape and try to return to Defiance.
With most of the McCawleys now dead, Pilar, Alak and baby Luke manage to escape. Pilar finds a trailer in the wilderness and promptly kills the occupants. When Alak awakes in the night, Pilar and the baby are nowhere to be found. In Defiance, Doc Yewl tries to mend the newly arrived purple-skinned alien, Kindzi, though she does so reluctantly. She knows them as an early Votan race known as the Omec, vicious creatures known for eating those they conquer. Kindzi's father T'evkin is soon in town and Amanda has a proposition for him: they will return his daughter provided they share the gulanite. Stahma and Dalak Tarr meanwhile have to deal with General Rahm Tak who wants them to be his spies in the city.
Nolan and Irisa are rescued from their underground confinement by a mysterious force, just in time to discover that enemy forces are marching on the town.
Nolan & Amanda plan escape after they're captured while excavating a buried weapons cache. Meanwhile Berlin sees an opportunity for revenge against Irisa while investigating a Votanis Collective bombing in the heart of Defiance. Stahma's clandestine relationship with T'evgin, the mysterious Omec leader, takes a turn.
While Nolan & Irisa fall into an unexpected and potentially fatal tour of their own past, Amanda & Doc Yewll enlist T'evgin to help rescue them. Datak & Stahma prepare a decisive move against Votanis Collective general Rahm Tak.
Nolan and Berlin pursue the Tarrs, their connection to the Votanis Collective exposed; Alak faces his future as a father.
A visiting handsome arms dealer changes Defiance's fortunes, and divides Amanda, Nolan and Berlin. Nolan recruits a militia to fight the oncoming Votanis Collective army, but the people of Defiance need convincing to fight what may be an unwinnable war; Datak and Alak have a reckoning; Stahma's presence causes strife among the mysterious Omec.
Defiance is under siege. Nolan, Amanda, Irisa, and the militia defend the town against a Votanis Collective incursion. Datak, recalling his father's chilling lessons, makes a pivotal decision. Stahma takes an unexpected trip.
Following a gruesome murder, Nolan and Irisa hunt the unusual beast loose in Defiance, and Doc Yewll investigates the surprising victim. Amanda resists welcoming back Stahma and T'evgin learns an unsettling truth about his daughter.
Over Nolan's skepticism, Amanda welcomes an encouraging Votanis Collective delegation to Defiance. Stahma's loyalties are tested by an unexpected arrival and T'evgin takes another step towards acclimating to life on Earth.
After Nolan is unexpectedly freed from Votanis Collective custody, Amanda, Irisa, and Berlin hurry to free him from Kindzi's clutches. Datak regrets seeking Doc Yewll's help against the Omec. Nolan witnesses something startling in the mines.
Nolan, Amanda, and Irisa search for a way to stop invulnerable Kindzi from waking and transporting more Omec to Earth. Datak seeks escape from a deadly Omec compound. Stahma implores Alak for forgiveness before it's too late.
With Omec on the loose, hunting Defiance citizens, Nolan, Amanda, Irisa, Datak, Stahma, Berlin, and Doc Yewll undertake a potential suicide mission to end the Omec threat once and for all.
