There are two different cases THE CASE OF THE MISSING BULLET and THE CASE OF THE INVISIBLE BULLET
THE CASE OF THE MISSING BULLET aired in 1998. In this case Daya Sir is accused of murder. THE CASE OF THE INVISIBLE BULLET aired in 2002. In this case Dr Salunkhe is unable to find the bullet in the Victim's body which has no exit wound. He is accused by ACP for hiding the bullet to save the suspects who were his friends.
I saw THE CASE OF THE UNDERCOVER COP just once. Let me see what I can recollect. ACP with team is visiting a jail where they find a very young prisoner. He is accused of trading in drugs. Speaking with him ACP understands that he is a small fish and the master minds are out in the open. So Abhi Sir disguises as a drug dealer to find the master minds. Thats the crux of the case. You can check this thread to see if vid is available or request for the same.
