I personally have never read any of the books of this series or even watched Divergent yet so for anyone like me who has not been keeping up with the books or film here is a quick recap to get you up to date before you watch the newest trailer after the jump –
Divergent – The story takes place in a dystopian post-apocalyptic version of Chicago where people are divided into distinct factions based on human virtues. Beatrice Prior is warned that she is Divergent and thus will never fit into any one of the factions and soon learns that a sinister plot is brewing in her seemingly perfect society.
Insurgent – Following the events of the previous installment, Tris must confront her inner demons and continue her fight against a powerful alliance which threatens to tear her society apart, with the help from others on her side
Insurgent is scheduled to be released on March 20, 2015.
The film stars Octavia Spencer (the Help, Bad Santa, Pulse) and Naomi Watts (the Ring 2002, Funny Games 2007 King Kong 2005, BirdMan 2015)
