Soon it is revealed that Gopi Krishnan is a corrupt assistant town planner using a government vehicle to come on holiday in Tamil Nadu during his duty hours.

In reality, Sukumaran is in disguise and is actually a vigilance officer named Nandhakumar trying to arrest Gopi Krishnan in a corruption case.

[1] Sify called the film "above average" and said: "Oru Naal Varum handles a relevant issue, but the problem here is the way it has been told.

Sadly, he transforms into somebody else just before intermission: as if to do justice to his superstar image ... Oru Naal Varum may be a well intended social satire but it ends up as a conundrum".
