Lionsgate released the first trailer for "The Divergent Series: Allegiant" and it shows Tris and Four in a romantic setup. Watch it here!

The official trailer named "Heights" will surely give fans of Tris (Shailene Woodley) and Four (Theo James) the case of the fuzzies as the two are seen climbing up an abandoned building to ultimately share a kiss.

Watch the official minute-long trailer below:

As the two are climbing up, Tris points out Four's former fears.

"What are you, afraid of heights?" Tris asks. To which Four denies.

"Sometimes when I look past the wall, I think that I can see something out there," Tris tells Four. "Do you?"

"I am looking, I'm just not seeing what you're seeing," he answers. After they agree to scale the wall to go outside, they then share a passionate kiss in the sunset.

"Allegiant" is the third movie for "The Divergent Series," which is based on author Veronica Roth's book series of the same name. The last book has been split into two parts with this movie being the first. The fourth movie, "The Divergent Series: Ascendant," will be slated for a 2017 release.

The movie follows after the events of "Insurgent" where Tris and Four escape Chicago by climbing up the wall. They venture outside it for the first time in their lives and discover that there is a lot more to what lies behind it.

"Once outside, old discoveries are quickly rendered meaningless with the revelation of shocking new truths," part of the official synopsis say. "Tris and Four must quickly decide who they can trust as a ruthless battle ignites beyond the walls of Chicago which threatens all of humanity. In order to survive, Tris will be forced to make impossible choices about courage, allegiance, sacrifice and love."

Book readers know what will happen to Tris in the series and fans have been clamoring to have it changed to give it a "happier ending." The fourth movie's tagline "The End Is Never What You Expect" may hint that there may have been changes made.

Author Veronica Roth reacted to the changes as the last two movies were previously called "Divergent: Allegiant -- Part 1" and "Divergent: Allegiant -- Part 2" back then.

"I know changes always make fans of the books - and the author! - nervous, but hopefully the characters we know (and love. Or sometimes love to hate?) will still be intact, which is really the important thing," she said. However it is not clear if the ending has been changed.

"The Divergent Series: Allegiant" is coming to US theaters on March 18. The movie also stars Ansel Elgort as Caleb, Miles Teller as Peter, Zoe Kravitz as Christina, Naomi Watts as Evelyn and Jeff Daniels as David..
