The plot revolves around Velan (Mugen Rao), who gets into the bad books of his father Palanisamy (Prabhu), a big shot in his village, due to his privileged behavior. He falls in love with his college friend Ananya (Meenakshi Govindarajan), a Malayali. A mix-up causes her father to fix Velan's match with Vidusha (Maria Vincent), who is also a Malayali girl from her college. When Vidusha's lover Velan and Dineshan (Soori) clear up this confusion without hurting her father, especially when the girl's father Ananda Kuttan (Thambi Ramaiah) and Veluchamy (Hareesh Peradi), who resents the Velan family, plot to embarrass Palanisamy.
The soundtrack and score is composed by Gopi Sundar, and the album featured four songs. The audio rights were acquired by Think Music. The song "Sathiyama Sollurandi" is based on Mugen Rao's single of the same name.[5]
Suganth of The Times of India rated the film with 2.5/5 stars, stating that "Velan exists somewhere in between these two experiences. It is not a film one can whole-heartedly recommend, but at the same time, it is not exactly bad. Is it glass-half-full or glass-half-empty for you?"[8]Sify gave a rating of 3 out on 5 and wrote, "Velan is not a groundbreaking attempt in Tamil cinema but it's not a film that is difficult to sit through. It's a typical rural entertainer with a predictable screenplay but the comedy and emotions work!"[9] Bhuvanesh Chandar of Cinema Express wrote, "In commercial family entertainers like Velan, at least one of the many elements cooked together should work to pull in the audience. Sadly, except for the interval block, none of the scenes works in its favour. To all poorly cooked commercial entertainers, Velan screams "Sema Killi!""[10]
