In Main Aisa Hi Hoon, Ajay Devgan playing a retarded character, a man who has the brain of a child, a man who also has his own child – a seven-year-old daughter. He loves his daughter and lives for her. But then a situation arises in which his ability to bring up his daughter is questioned and he comes to the point of losing her. The film tells the story of this father’s court fight to keep his daughter.
Inderneel or Neel (Ajay Devgan) is not a usual man. He is like a child inside a man’s body. His little world consists of his cute daughter Gungun, who is the apple of his eye. Neel’s marriage with Gungun’s mother Maya (Esha Deol) could not last long and she walked out of his life after the birth of Gungun.
Seven years have passed since then, and Neel and his daughter have got along fine in their happy, jolly little world. But then, on Gungun’s seventh birthday, Maya’s father (or Gungun’s nana) Dayanath comes to see his granddaughter. He comes from London to claim the guardianship of Gungun on the grounds that her retarded father, Neel, is not capable of bringing her up.
Desperate to keep his daughter with himself, Neel searches for the best lawyer in town and comes across Neeti (Sushmita Sen). Neeti is a promising lawyer but she is also a very unlikely person to take his case. She has neglected her own son for whom she could never take out time from her busy life.
Neeti is uninterested in taking Neel’s case. But his persistence, his honesty and innocence melt her heart. She knows it is not an easy case. Gungun’s nana has many strong points and arguments to present in the court of law. Neeti takes the challenge and decides to fight a tough battle. In the course, she also learns the values of good parenting from Neel’s unfathomable love for his daughter.
