A body of a woman, Emma, in a black party dress is found in a dumpster. Her head is wrapped in packing tape. When the ME examines the body, he finds that her eye lids have been removed. This leads Mac to a recently released serial killer with the same MO. The second case possibly involves the Russian mafia. Lindsay and Danny team up to unravel the truth.

The investigation to Mac's botched bust continues. Meanwhile, a guy who crashed his bride-to-be's bachelor party, is found dead in the restroom, and the eye witness testimonies point to tennis star John McEnroe.
