You may watch below the trailer of “Bylaw”, the next episode of Terra Nova:

“The colony falls victim to its first murder, and Jim and Taylor must find the perpetrator. Also, Skye helps Josh find a way to get Kira, his girlfriend from 2149, to the past, while Elisabeth and Zoe race to help an unborn Ankylosaurus survive.”

That new world isn’t any better than ours, murderers are still roaming around…
