Sir Sir Sarla explores the complexities of love through three interconnected lives. University students Sarla and Phanidhar share a deep affection for their professor, Palekar, but in very different ways. Sarla is romantically in love with him and dreams of a future together, while Phanidhar's feelings are a conflicted mix of admiration, resentment, and blame. He believes the professor's decision to distance Sarla and encourage her marriage to Keshav has left all their lives unfulfilled. As Sarla finds herself neglected in her marriage, old wounds resurface, leading to a series of confrontations that leave the audience questioning whether Professor Palekar's choices were truly the right ones.
