The BBC will be investigating animal agriculture in a program called The Dark Side of Dairy.
The one-off episode is part of BBC Scotland's Disclosure series - a current affairs show 'examining the issues affecting the lives of people around Scotland'.
It will be available to watch on BBC iplayer after it screens on September 10.
According to the broadcaster: "Investigative journalist Samantha Poling takes a journey into the controversial world of live animal exports.
"She uncovers some shocking truths about what happens to the male calves the Scottish dairy industry has no use for.
"And she goes on the trail of a live cattle shipment across Europe to see for herself the long journeys they endure."
'Share the horrific truth'
Vegan activist Chris Hines, Founder of animal rights organization Virtue, shared a video of the trailer on social media.
He wrote: "Share this video and let's make sure the world watches and learns the truth about this horrific industry."
