Annmariya Kalippilaanu revolves around Annmariya, an imaginative and fiercely determined fourth-grader living in Kerala. Nicknamed "Kalippilaanu" for her ferocious temper, Annmariya’s greatest passion is learning karate, a wish consistently thwarted by her overprotective parents. Her world shifts when she crosses paths with Gireesh, a slick, small-time con artist and unemployed youth struggling to scrape together money to fund his girlfriend’s escape to Dubai. Gireesh’s life is a chaotic mess of petty scams, gambling debts, and constant dodging of local loan sharks who are relentlessly pursuing him for repayment.Annmariya hires Gireesh for a very specific, covert mission: to physically threaten and teach a harsh lesson to her strict, uncompassionate
school principal, PT Sir. She offers him a stolen golden chain as an advance payment. Initially, Gireesh treats the child’s demand as an absurd joke. However, faced with mounting financial desperation and desperate threats from his creditors, he reluctantly agrees to the bizarre contract. As Gireesh attempts to execute the plan, he repeatedly bungles the execution, leading to a series of escalating comedic mishaps and disastrous misunderstandings that draw them both into deeper trouble.Despite their unconventional and rocky start, an unexpected bond slowly forms between the cynical con man and the spirited, defiant schoolgirl. Gireesh begins to see his own lost innocence and lack of direction reflected in Annmariya’s stubborn pursuit of her dreams. Conversely, Annmariya finds a loyal, albeit flawed, protector in Gireesh. When the truth behind Annmariya’s deep-seated resentment toward her school environment and the physical abuse she suffers at the hands of the principal comes to light, Gireesh’s motivations shift dramatically from financial gain to genuine moral outrage. He realizes that PT Sir is a dangerous predator who preys on vulnerable students.Motivated by newfound courage and a fierce sense of protective responsibility, Gireesh decides to abandon his selfish ways. He confronts the principal directly, exposing the systemic cruelty hidden within the school walls. Simultaneously, Gireesh faces his own
personal demons, squaring off against the ruthless loan sharks in a high-stakes climax. Through a blend of clever trickery and genuine bravery, Gireesh manages to rescue Annmariya from danger, humiliate the corrupt principal, and settle his debts. In the aftermath, Annmariya finally receives the parental understanding and karate lessons she desired, while Gireesh transforms into a responsible, reformed man, forever changed by his friendship with the fierce little girl.
