Orange movie is all about Yakobi (Kalabhavan Mani) who lost his parents in his childhood. He worked in a place called Kambam in a dairy farm. There he drived his own lorry on contract basis. The name of his vehicles was orange. At Kambam he loved a girl, Saritha and married her. His sisters neither relatives did not know about this marriage. Later Saritha gave birth to babygirl Diya. Whenever he reached his native place his relatives enquired why he was staying as a bachelor.
As usual when Yakobi was returning back to Kambam after visiting his native place, a man asked him a free lift. While continuing their journey Yakobi came to know that his name was Muthu and he was coming to attend an interview for a job in the dairy farm where Yakobi is working. But unfortunately they could not reach the farm within time. Yakobi some how made arrangements to get a temporary job for Muthu in the diary farm. One day Yakobi met one of his old friends Baboottan (Biju Menon). Yakobi invited him to his house and it is from there the story turns.
