Selva is a college student. Raasathi is Deva's cousin and love interest and was betrothed to marry him since childhood. Deva's family has a rivalry with Ramasamy's younger brother's family.

All is well until Deva's maternal grandmother becomes severely ill. She meets with Ramasamy on her deathbed and reveals a secret: Deva is not their child. During her delivery, Lakshmi's son was stillborn. As a result, Lakshmi's mother switched the stillborn baby with an infant Deva, whom she found abandoned in a train latrine. This causes Ramasamy to kick out Deva from his home and disown him, as Ramasamy is a staunch casteist. This causes the rich Deva to become a pauper, but he loves his parents more than ever.

Meanwhile, Rasathi's brother arranges her wedding with Deva's cousin, but she consumes poison and blackmails her family that she will die unless Deva marries her. Deva marries her takes her to the hospital, but she dies on the way, devastating Deva. Shortly after her funeral, Selva comes back home and heavily criticizes Ramasamy for mistreating Deva. He leaves home to find Deva and reunites with him. Later on, Ramasamy and Selva are kidnapped by Deva's cousins and are blackmailed to sign over their properties. Deva comes and rescues them. Ramasamy and entire village beg Deva to return and take his place as Ramasamy's heir. However, Deva refuses and leaves forever in a train latrine while everyone tries to look for him.

Prathyusha was supposed to pair with Abbas but due to her demise she was reported to have been replaced by Radha who earlier appeared in Sundhara Travels; however Bharathi later removed the love angle of Abbas from the film.[2]

Soundtrack was composed by S. A. Rajkumar and lyrics were written by Pa. Vijay, Nandalala and Kalaikumar.[3]

Indiaglitz wrote, "Bharathi has tried to come out with a movie on father-son relationship, targetting the family audience. When fast-paced scripts are the order of the day in Tamil filmdom, the narration seems slow in Manasthan."[4] Sify wrote "Manasthan is as stale as day before yesterday?s sambarand can be avoided."[5] Visual Dasan of Kalki wrote that a fan who ignores Manasthan, where there is no innovation in anything be it cinematography, music or direction, is really a knowledgeable.[6] K. N. Vijiyan of New Straits Times wrote, "If you like family-based stories, you are unlikely to be disappointed with Manasthan".[2]
