Terra Nova Spoilers: Back To The Future! 19.10.2011. @ 17:56 MatejJelic I'm sure we all wondered if Terra Nova be spending any time back in 2149, or will all the time be spent in 85 million BCE? Hopefully not, and Ausiello confirmed it. The show will be travelling back to the future, although most of storytelling takes place in Terra Nova. Toward the end of the season, the Sixer conspiracy comes to a head and this takes us to some scenes that play out in 2149.
