From the minds behind Battlestar Galactica and Farscape comes one of the most hotly anticipated series of 2013. After losing their star system, an alien race known as the Votans have arrived on Earth, searching for a new home. Negotiations with the humans have failed, and supplies are running low – the Votans are desperate and there’s only one thing left to do: wage war and claim Earth. Nowhere is safe and it is up to Jeb Nolan, Chief Lawkeeper of a refugee camp named Defiance, to protect his town from the deadly clashes between Man and Votan, as well as other mysterious and unwanted visitors. Political drama, action thriller, science-fiction – Defiance brings together all these elements into a scintillating blend of entertainment that will not slow down for one minute.
