Suresh Gopi is a natural at playing the role of police officers- quite ones, loud ones, angry ones, elegant ones. He also is very good at playing politicians- good one, bad one, shrewd one, ambitious ones...In Detective, he gets to do both- play the role of a cop and a politician!!! Needless to say, he does them both in style! After a long time, Suresh Gopi is playing dual roles in the film. In Detective, he is Mohan Kumar, a young and ambitious politician who has a seemingly perfect life until his beautiful and equally ambitious wife Reshmi ends up dead. The reason behind the death appears to be suicide. The cops also find a suicide note.
