Manathodu Mazhaikalam movie tells Siva (Shaam) and Sathya (Nithyadas) who are collegemates. She is a good friend of Siva. She is a good friend of Siva. She is always with him, both in his happy and sad moments. When he is in a tight corner, Sathya with the help of her father, helps Siva to come out it unscathed. Their friendship continues even after their college days.
The parents of Siva and Sathya mistake their friendship as an affair. The two refuse and make it clear that they are platonic friends with oneness in their thoughts, but no plutonic thoughts.
In the course of time, Siva marries Sruthy (Samiksha) and Sathya marries Karthik (Jaya Surya). The problems and resultant consequences due to their affection for each other, forms the screenplay of the story.
