Musician Rory Feek is honoring the memory of his late wife Joey, who died in March, with a documentary, To Joey With Love.

On their wedding anniversary Thursday, Feek shared a trailer for the film, which features home video and follows the emotional journey the married country singing duo endured after Joey was diagnosed with cancer two and a half years ago, months before their daughter’s birth in 2014.

Rory posted the trailer on his website, along with a powerful blog post about his wife and what he hopes people will take away from the film.

“Most people know Joey and I for the five months we spent in Indiana — the beautiful, terrible days and weeks last fall and winter that we intimately shared through my blog posts,” he wrote. “They got to see Joey die. To see her face death bravely and pass to the other side with honor. But I’d like for people to have the chance to see my wife live. To see the incredible woman that she was before the doctors said there was nothing more they could do… so they can better understand the amazing impact she’s had on me and everyone around her after she learned that the end was coming.”

To Joey, With Love will be released for one night only in theaters on Sept. 20.
