Manu Uncle

Four children, called "Gang of Four" - Renu (10), Sanku (12), Dany (11) and Ekru (5) go sightseeing. At a museum, they spot a jeep with a small silver horse fixed on the bonnet. Ekru sees a man tinkering with something in front of the Crown of Marthanda Varma. Immediately after the Crown is stolen. An attempt to steal the Royal Sword of Marthanda Varma is foiled by Manu, lovingly called Manu Uncle. In the action against the robbers, the grandfather of Renu and Sanku is killed. With the help of an orphan boy, Khader, the children reach the shore where the robbers are selling the stolen antiques. By tying the boats, they make the robbers' escape impossible and overpower them.
