Sci-fi heroine Beatrice Prior is returning to our screens next year in Divergent Series: Allegiant, the third installment of the Divergent series, and, if the trailer is anything to go by, it promises to be one of the most exciting movies in the franchise so far.

We’ve got explosions. We’ve got a love story. We’ve got guns, and we’ve got some serious humanity-saving missions to complete. What more could one ask for?

The original movie, Divergent, was released in 2014. The follow up, Insurgent, was released this year. So far the movies have been huge box office successes, grossing $288.9 and $297 million respectively.

Although there are only three novels, the final, also named Allegiant, will be split into two separate films. This is a tactic we’ve seen in recent years with big hitters like The Hunger Games and Twilight, who also took the same route of splitting the final novel into two parts.

The series is set in a dystopian reality years in the future, where humans are separated into factions based on virtues. Tris, who doesn’t fit into any one group, is known as a ‘divergent.’

In the penultimate movie, Tris (Shailene Woodley) and Four (Theo James) will enter protective custody by an agency called the Burea of Genetic Welfare, after venturing into the world beyond ‘the fence.’ With the threat of Chicago being destroyed and everyone they know being killed, they will be responsible for saving the city.

Since viewing the new trailer, some fans of the original series of novels by Veronica Roth, have expressed concern on social media that Allegiant is going to deviate from the original plot.
