Kappal is an Tamil film directed by Karthik G. Krish, a former assistant of Shankar. Produced by I Studios Entertainment, the film features Vaibhav and Sonam Bajwa in the lead roles, while Arjunan and Karunakaran appear in supporting roles.
Five little friends take inspiration from an elderly figure to never part ways. They take the oath under the condition that they will not get married at all - for the fear that a girl might break their friendship. They grow up, and continue to follow the same principle, except Vasu, who doesn't want to give into this humbug, yet does so for the sake of friendship.
