In the latest trailer for "Insurgent," the sequel to "Divergent," Tris (Shailene Woodley) has the weight of the world on her shoulders.

"You are the key to rescue what little civilization we have left," brother Caleb (Ansel Elgort) tells her.

In "Insurgent," all-out war threatens to break out as factions are pitted against each other. Tris and her fellow divergent, Four (Theo James), face off against the manipulative Jeanine Matthews (Kate Winslet), who wants to hunt their kind down to "maintain social order."

The trailer features a bunch of new footage, with glimpses at other characters, including Octavia Spencer's Johanna Reyes, Miles Teller's Peter Hayes, and Daniel Dae Kim's Jack Kang. "Insurgent" hits theaters Feb. 25.
