Ab Tak Chhappan 2 opens to encounter specialist Sadhu Agashe (Nana Patekar) proclaiming what he did was right. The film then goes into flashback, where we are shown what happened a few months back. Away from Mumbai, with a few cases pending against him, Sadhu now leads a peaceful life in his village (Goa) with his son Aman, mourning the loss of his wife. He cooks, lives in a house by the river and listens to his son playing the piano. However, his retired phase comes to a halt, when ex-police commissioner (Mohan Agashe) convinces Sadhu to get back on the job on the home minister's (Vikram Gokhale) request to tackle Mumbai's escalating crime scene.
