for KING + COUNTRY's Joel Smallbone Brings His Family's Story to Screen in Unsung Hero Trailer (Exclusive)

Joel Smallbone is taking his family's story to the big screen.

On Tuesday, Lionsgate and Kingdom Story Company shared the brand-new trailer — exclusive to PEOPLE – for for KING & COUNTRY's new movie Unsung Hero, a film that traces his family's real-life move to the United States from Australia in the 1990s.

As the family struggles to establish themselves in a new country, their daughter Rebecca St. James begins receiving attention for her impressive singing ability.

The entire Smallbone family then bands together to help keep the family financially afloat, shown raking leaves and doing yardwork together to make money. Their hard work eventually pays off; Rebecca's career grows until she is a popular recording artist.

The trailer even cheekily teases fame to come for for KING + COUNTRY members Joel and his brother Luke Smallbone, shown as children in the film, telling their father that they want a record deal too.

"Unsung Hero follows David Smallbone as he moves his family from Down Under to the States, searching for a brighter future after his successful music company collapses," reads an official synopsis for the movie. "With nothing more than their seven children, suitcases, and their love of music, David and his pregnant wife Helen (Daisy Betts) set out to rebuild their lives."

"With their own dreams on hold, David and Helen begin to realize the musical prowess in their children," the synopsis adds, hinting at the future success of Rebecca and for KING + COUNTRY."
