Terra Nova is an American science fiction drama television series. It aired one season from September 26 to December 19, 2011. The series documents the Shannon family's experiences as they establish themselves as members of a colony, set up 85 million years in the Earth's past, fleeing the dystopian overpopulated and hyperpolluted present of the mid-22nd century. The series is based on an idea by British writer Kelly Marcel and was executive produced by Steven Spielberg. On March 5, 2012, Fox announced that the show was canceled.
The series is initially set in 2149, when overpopulation and declining air quality threaten all life on Earth. When scientists discover a temporal rift permitting (one-way) human transmission, they initiate a series of "pilgrimages" to a parallel "time stream" resembling Earth's Cretaceous Period. The series focuses primarily on police officer James "Jim" Shannon, his wife Elisabeth, and their three children Josh, Maddy, and Zoe, as they join the colony there, named "Terra Nova" (Latin for "New Earth" or "New World").
Elisabeth Shannon is chosen to join Terra Nova for her medical expertise, and her two older children with her. Her husband, imprisoned for violating population control by harbouring a third child and assaulting an official agent to protect his young daughter, stows away to join them and eventually convinces the colony's leader, Commander Nathaniel Taylor, that his own police expertise is of use to the administration.
