Basu is explaining the butterfly effect. It's a black comedy, like we saw in the trailer people getting hit by trucks, bus, and what not. Abhishek Bachchan (player Red) is a fun kidnapper who has his own internal battles to fight. One will hate Fatima's character to the core as she never fails to take advantage of the hopeless romantic Rajkumar Rao(player green). The nurse and Rohit (the sky is pink) (player blue) become companions of an unplanned journey and learn to enjoy what comes their way, they are probably the only characters who are happy about this change. Now let's talk about the Aditya's character (player yellow), an optimist and another romantic looking for blind dates on matrimonial sites, just not hopeless and an artist who is enjoying doing comedy shows with his ventriloquist. Pankaj Tripathi is the catalyst/ dice, who sets things into motion and let's the story unfold. Even though you won't see his character with enough screen time, you will enjoy every bit of it. Oh, don't forget the background music "Oh Beta Ji", it's a key to this game of Ludo. Basu has kept up with the esthetics as well, with each player by bringing in strong representation of each their respective colour in their stories.

PS: Basu himself is in the film narrating the story at many points.
