Youth-led investigation agency Volume 6 Private Eyes is on the brink of shutting down its operations for good following a period of stagnation. That's until a new client shows up at HQ with a challenging new case, one never taken on before by the girls behind one of Chennai's most prominent detective agencies (well, formerly, at least). Madhavan Srinivasan was a taciturn, reserved man with an enigmatic past. One day, he's found dead at his Basil Street residence with no signs of a break-in. Can the intrepid investigators discover who killed Madhavan and unearth the secrets he left behind, all whilst dealing with a detective from the police who'll do anything he can to stall their investigation?
