The 2-minute-9-second trailer is packed with intriguing details. Sharing the trailer on X (formerly Twitter), Vikram wrote, "Witness the Son of Gold, mine through history with sacrifice, sweat, and bloodshed."
The trailer begins with Parvathy Thiruvothu's character questioning Vikram about what troubles his mind, suggesting he may be struggling with his mental health. Shortly after, Lord Clement, a British officer, arrives in the village, seeking gold with the villagers' assistance.
One man ominously predicts that searching for the gold is tantamount to searching for death. Malavika Mohanan plays Aarathi, a supposed sorceress determined to protect the land from exploitation. The trailer concludes with Vikram, covered in gold dust, standing alongside his people.
