Chloe Moretz (The Miseducation of Cameron Post)

A trailer has been released for the upcoming film The Miseducation of Cameron Post, directed by Desiree Akhavan and starring Chloë Grace Moretz. Watch the video below.

The film – based on the 2012 novel of the same name by Emily M. Danfort – follows Moretz’s title character, Cameron Post, who gets caught having sex with the school prom queen.

Post is then sent away to a gay conversion therapy camp by her conservative aunt and uncle.

In January, the movie won the grand jury prize at the Sundance Film Festival.

The trailer shows Post as she signs papers to be taken a gay conversion therapy camp, with an official telling her: “Now you’re officially a disciple of God’s promise, welcome!”

The video shows Post as she navigates her time at the camp, where she is told she must overcome her “struggle” with the “sin of same-sex attraction.”

Along the way, she makes friends with Adam and Jane from the camp, through smoking weed and sharing stories of their experience of conversion therapy.

However, the video also shows Post expressing anger over being in the camp at all – “I’m tired of feeling disgusted with myself,” she says at one point – and hints at a possible romance.

Moretz spoke out about the harsh realities of gay conversion camps in America at the film’s premiere in January.

She told AFP: “The (Trump) administration actually completely believes in conversion therapy.

“Mike Pence tried to get it state-funded when he was Senator, so it is a very real problem.”

Some twelve states in the US – including New Jersey, California, Oregon, and Nevada – currently have bans on gay conversion therapy.

The Miseducation of Cameron Post will be released in the US on August 3, and in the UK on August 31 this year.

In August 2014, a high school in Delaware removed all summer reading for incoming freshmen because one of the books on the reading list was the novel The Miseducation of Cameron Post.

Parents had complained about the book’s content.

Board president Andy Lewis told WBOC 16 the book was removed because there was no process to evaluate it following complaints.

The board cited profanity as the reason for banning the book. Other books on the list, however, also used curse words.
