Akash's Birthday party is going on at Monica's farmhouse, and they are playing a card game called Go Fish. Soon a chit comes up while playing the game that says that "M" will die that night. Everyone thinks this is a joke and brushes it aside, but things soon turn sour when Monica dies. CID realise that Monica died in a closed room, locked from the inside with there is no entry or exit that the killer could have escaped from- which means that one of the 7 friends present is the killer.
