Years after successfully (and precariously) managing his triple marital life, Shiv Kumar finds himself in an even more elaborate web of deceit in 'Kis Kisko Pyaar Karoon 2'. While he has, through sheer luck and ingenious scheduling, kept his three wives – Anjali, Simran, and Juhi – in the dark, his carefully constructed world begins to unravel. The film opens with Shiv enjoying a semblance of normalcy, albeit one dictated by a meticulous daily routine that sees him commuting between three different households and maintaining three distinct personas. However, the equilibrium is shattered when a new, vivacious, and highly ambitious colleague, Tanya, joins his company. Drawn to her charm and intelligence, Shiv, against his better judgment, finds himself developing feelings for her, further complicating his already stretched emotional and logistical resources. Adding to his woes, his now teenage children from each marriage are growing up and becoming more inquisitive. One of his sons, Rohan, a budding detective-enthusiast, starts noticing peculiar patterns in his father's schedule, unexplained absences, and sudden mood shifts. His amateur sleuthing leads him closer to the truth, inadvertently involving his friends (who are, unknown to him, his half-siblings). As Shiv attempts to juggle a potential fourth romantic involvement with Tanya, evade Rohan's increasingly sharp observations, and maintain the delicate balance between Anjali, Simran, and Juhi, his secret life teeters on the brink of collapse. A series of hilarious misunderstandings, close calls, and mistaken identities ensue, particularly during a family-wide company retreat that all four women (and their respective children) unexpectedly attend. Shiv's desperate attempts to keep them apart and prevent the inevitable collision form the core of the comedic chaos, leading to a climactic sequence where all his lies are on the verge of being exposed in the most public and embarrassing manner possible, forcing him to confront the consequences of his choices.
