Each episode of C.I.D. starts with a member of the team describing the events of a crime, which is followed by the crime being occurred, and the C.I.D being called out to interrogate the case. Occasionally, while the crime is being committed, the team is usually having fun in the bureau; such as playing chess, talking about Cricket, or picking on Inspector Fredericks for his actions. The C.I.D. team then goes to the crime scene, and starts their search for evidence. They always believe in one statement: Every criminal always leaves something behind. They search the setting until they find something, even the smallest thing, such as a strand of hair. The body, if it is a murder case, is taken to the forensic lab, where Dr. Salunke and his assistant study the body. Dr. Salunke tells interesting thing on how the person may have died. He may have been stabbed by a knife, but he may be killed by poison. The C.I.D. team interrogates all the witnesses. After a lot of hard work, the C.I.D. team solves the case and catches the criminal.
