Defiance is an American science fiction television series developed by Rockne S. O'Bannon. The series was produced in collaboration with Trion who produced a Defiance MMO video game. Defiance stars Grant Bowler as Joshua Nolan, the local lawman in a post-apocalyptic city known as Defiance. The series was broadcasted in the United States on the cable channel Syfy and in the U.K. on SyFy.co.uk; it was produced by Universal Cable Productions.
Defiance opens up with a flashback scene, set in the present day (2012/2013), which is narrated by main character Joshua Nolan who explains exactly what happened to Earth. Alien ships entered Earth’s atmosphere seeking a new home after their own solar system was destroyed. They call themselves "Votans," and shortly after their arrival, negotiations begin between the aliens and the government(s) of Earth. After six years of negotiation, no agreement has been reached and a war begins between the two sides. By this time, Joshua Nolan (now sixteen years old) has enlisted in the military to fight for his people against these invading aliens.
In an air battle, the huge alien ships in the atmosphere are destroyed and they plummet down to Earth. However, contained within the wreckage of these vessels are terraformers which begin to transform the planet. This transformation was described as scorching the earth, creating vast chasms in the ground, and resulting in layers upon layers of debris and dirt forming on the surface of the planet; effectively burying major cities. It is then revealed that there is not one alien species but many, with Votan merely being the collective name they have chosen. One such species, the “Castithans," are alien but look entirely human.
As the war continues both sides come to realize that neither can win and they have only one joint priority: survival. With this realization, the war comes to an end and both sides focus on licking their wounds and attempting to rebuild. Which brings us to the time when the series will be set (approximately 30-50 years in the future). Joshua Nolan returns to his hometown of St. Louis, to find it no longer looks like the city he left nor is it called that anymore. St Louis is now Defiance. I have been told that Defiance is a kind of refugee camp; the one refuge for civilization in this new world where everything has changed. Realizing that his expertise from the military is needed in Defiance, Joshua Nolan takes the role of the “Chief Lawkeeper," making him responsible for keeping the residents of Defiance safe from the scavengers, dangerous Votans and other criminals that will occasionally breeze through the town.

Stahma is not satisfied with Datak’s station in Defiance and feels he (and by extension, She) should have more power. She comes from old money and is very cunning and arrogant, with a sense of entitlement.
