Hot Water Murders

CID comes across two murders of Ujjwal and Monica that are connected to each other. Both Ujjwal and Monica were linked to a dead businessman Deven who had died in a water accident some time ago. Cops feel somebody is taking revenge on Deven's behalf and suspect his caretaker Aditi and his ex-wife Rewa. CID zeroes on to Rewa and she is almost arrested. But they soon realize that the person behind these murders is somebody they never thought of.
