Duck Dynasty ’s Uncle Si Robertson stars in Stephen Baldwin’s war drama Faith of Our Fathers.

Directed by Carey Scott, the movie is about two sons on a road trip to learn about their fathers. It is set in 1969 during Vietnam the War, where the two young fathers report to duty. One father has a strong faith and the other one is a cynic. Years later, their sons, Wayne and John Paul, meet as strangers and they form a friendship as they try to retrace their fathers’ footsteps.

Guided by handwritten letters from their fathers from the battlefield, they embark on an unforgettable journey to The Wall-the Vietnam Veterans Memorial in Washington, D.C. Along the way, they discover the devastation of war cannot break the love of a father for his son.

Si Robertson, a Vietnam veteran himself, says he is proud to be part of a movie that promotes patriotism.

The Duck Dynasty star, who plays a gas station clerk in the war drama, believes the movie is important because it shows the many sacrifices made by the men who fought in wars.

Si Robertson wrote on his Facebook page: “Faith of Our Fathers does its best to honor the men who gave up their lives for their country. Hey, it’s a must see Jack!”

Faith of Our Fathers, also starring Stephen Baldwin, Kevin Downes and David A.R. White, will premiere on July 1st on the 50th anniversary of the Vietnam War.
