With no double meaning dialogues or flashy song sequences shot abroad or 'high-voltage' stunt scenes, the film is an emotional journey between a father and daughter and their love towards each other.The USP of the movie is immaculate performance by Chiyaan Vikram. He plays a dotting father to a five-year-old daughter. But he is not the usual dad - he is an adult with the mental maturity of a five-year-old. The actor in Vikram seems to have taken it in his stride to deliver a power-packed performance.Matching him by scene-to-scene is young Sara who plays his daughter. The sequences involving Vikram and Sara are the major highlight of 'Deiva Thirumagal'.Anushka as an advocate and Amala Paul besides a huge star cast that includes Nasser, Santhanam and M S Bhaskar among others have given their best on screen.Krishna (Vikram), who has the mental maturity of a five-year-old, works in a chocolate factory in Ooty. His wife delivers a baby girl and dies. The girl, Nila (Sara) is brought up in his own way by Krishna.He showers all his love and care on her. But fate takes a quick turn. Nila's grandfather Rajendran (Sachin Khedkar), a powerful and influential man in society, enters the scene. Fearing that his grand daughter is not safe under a mentally-challenged dad, he takes away the girl from Krishna.
