This movie is supposed to be based on the real life Aarushi murder case that happened in Delhi , but the director has changed it to a action packed murder mystery that keeps us guessing about the identity of the murderer till the very end . The setting has been changed too--it's in Mumbai , and some of the characters are marathi who speak hindi in a highly marathi accented style . So , a young girl whose both parents are doctors is found murdered in her bedroom by her female servant one night . She was a hindu girl in love with a muslim boy , and it seems to be a straight forward case where the father caught her with her lover in her own bedroom and killed her in a drunken fit of anger as he was opposed to the inter religion relationship . The father ( played by Ashish Vidyarthi ) is duly convicted by the court . But he is an influential person whose friends raise hell and the case has to be reopened and given to the CBI . Enter CBI investigating officer Paraskar ( played by Kay Kay Menon ) . He immediately finds loopholes in the case , and starts reinvestigating it . His first hurdle---the girl's muslim lover has disappeared , and can't be found . Soon Paraskar finds other suspects for the murder , but runs into a bigger hurdle---the suspects are bumped off one by one by somebody , thus deepening the mystery . The personal life of the doctor parents of the murdered girl and their friends is also complicated by a string of infidelities , and nothing is as it seems.... It is Kay Kay Menon who holds the film together with a redoubtable performance , showing alternating shades of both toughness and humour in the same situation by making the audience smile at the same time his opponents are quivering in fear.... The performance of the rest of the cast ranges from vampish (by Meera Vashisht ) to crass ( by the actor who plays the marathi police inspector who originally investigated the case ) to understated ( by the murdered girl's mother played by Tisca Chopra ) . The action seems real , and the blows showered pack a punch . There are no songs and dances , and no really romantic scenes . In the end Kay Kay Menon assembles all characters ( those who are still alive at least , though many have been already bumped off ) in a room to unravel the mystery , just like Hercule Poirot does in Agatha Christie Novels . ....But the director is no Agatha Christie , and fails to end what could have been a gripping film in a convincing manner . I did not feel that the solution to the mystery was coherently presented , and the climax was most unimpressive . It in fact , unravelled some of the good work that the director had done in the earlier part of the film . Where the director scores is the distinctly unglamorous look of the film , which will keep the budget of the film low and the profits high even if the film has a modest run at the box office . The sets of the film have a dull colour , and the clothes worn by the cast are not flashy at all . Verdict on the film---Decent . Three stars .
