STORY: The lives of a happy family of three — Gautam Grover (Ashmit Patel), Puja Grover (Manjari Phadnis) and their daughter Dil— comes crashing down when an attractive paying guest Ada Saxena (Maheck Chahal ) comes to stay with them.REVIEW: When the peace and harmony of a simple household is threatened by the arrival of a seductress Ada and the lecherous, pesky neighbour Rana (Mukul Dev); it makes way for a murder mystery that top-notch encounter specialist police officer Lokhande (Arbaaz Khan) resolves to crack under any circumstances. The only problem he faces is the fact that everyone’s a suspect.Of all the things that have gone horribly wrong with this murder mystery, its background score tops the chart: annoying and so passé! The twists in the plot, which is typically the USP of any movie from the mystery genre, are predictable and defy logic. Despite the loopholes and some terrible acting, the first half of 'Nirdosh' is lot crispier than the stretched-beyond-imagination second half.Except for Mukul Dev’s sleazy and wife-beating act, all the other actors were a tad over the top. While the glam quotient was in place, acting, direction and story clearly were not.
