Anirudh, a successful but somewhat jaded real estate agent in his early forties, finds himself increasingly restless in his otherwise comfortable and predictable marriage to Divya, also in her early forties. Their life, while stable, has lost its spark, settling into a comfortable routine. The monotony is shattered with the arrival of Tanya, a vibrant and charming interior designer in her late twenties, who becomes Anirudh's client for a high-profile property deal. Flattered by her attention and captivated by her lively personality, Anirudh embarks on a clandestine flirtation that soon escalates into a full-blown affair, complete with secret rendezvous, fabricated excuses for late nights, and a web of lies he meticulously weaves for Divya. Meanwhile, Divya, sharp and intuitive, senses a shift in Anirudh's behavior. Feeling neglected and seeking intellectual stimulation, she reconnects with Rohan, a witty and thoughtful author from her college days. Rohan, who had always held a torch for Divya, offers her the attention and genuine conversation she misses, slowly developing an emotional connection with her that, while not physical, deeply challenges the boundaries of her marriage. The 'Do' in the title refers to these parallel narratives of emotional and physical entanglement. The two storylines converge dramatically during a prestigious property launch event, where Anirudh plans to unveil Tanya as a key design partner. Divya, accompanied by Rohan as her platonic escort, also attends. Through a series of near-misses, overheard conversations, and incriminating evidence, Anirudh's carefully constructed double life comes crashing down. The confrontation is explosive, as Divya not only exposes Anirudh's infidelity but also reveals her own emotional journey with Rohan, not as a tit-for-tat affair, but as a consequence of her husband's neglect. The film delves into the raw aftermath, exploring Anirudh's frantic efforts to salvage his marriage, Divya's agonizing decision between forgiveness and self-respect, and Rohan's steadfast but morally ambiguous presence. 'Pati Patni Aur Woh Do' is a poignant and often humorous exploration of modern relationships, infidelity, the yearning for connection, and the intricate dance of deception and revelation, leaving the audience to ponder the true meaning of commitment and whether a marriage can truly recover from such profound dual betrayals.
