Every version of Allegiant — the books & films, compared across media.
Allegiant follows Tris Prior through the fractures of a society built on factions — shattered by violence, power struggles, loss, and betrayal. When she is offered a chance to venture beyond the limits of everything she has known, Tris takes it. The same journey has been told as a novel and brought to screen as a 2016 film, each version tracing her passage from a broken world into an unknown one.
Yes. The 2016 film Allegiant is adapted from the novel Allegiant, which follows Tris Prior after her faction-based society is shattered by violence and betrayal and she seeks the world beyond its limits.
There are two versions covered here: the dystopian novel Allegiant and the 2016 action-adventure film Allegiant, both following Tris Prior's journey beyond her known world.
The novel Allegiant is the source story and gives the fullest account of Tris Prior's world and motivations; the 2016 film Allegiant is a good choice if you prefer a visual, action-driven telling.
