Kaval Kottam stars Vijayakanth as DSP Bharani, a fearless police officer. The film opens with Bharani dismantling a local smuggling ring run by a powerful don, Chakravarthy. Chakravarthy uses political connections to have Bharani transferred repeatedly, but Bharani continues to fight crime. The plot thickens when Bharani's own brother (played by Goundamani in a rare serious role) is manipulated into helping the villain. In the climax, Bharani storms the villain's fortress-like hideout (the "Kaval Kottam") and defeats him. The film is noted for its dialogue favoring police integrity and was a commercial success.
