The film
It starts with Rana and his best friend Janu who are climbing a mountain in bad weather. In the middle of a dense forest, they got separated and lost. Janu is lucky to be back home at last. But not with Rana. An extensive search was carried out. Rana not found. A week has passed. Rana's extended family decided to hold a tahlilan. Rana is considered unlikely to have survived and will surely die there. Dini can't accept that. As a mother, Dini doesn't want to just give up and still believes that her daughter Rana is still alive. Sure enough. After the tahlilan, Rana came home in the pouring rain.
