Season 2: Episode 6

When a man is found murdered in an elevator, Mac, Flack, Danny and Lindsay investigate a world where very young girls enjoy sexual encounters with much older men.

Stella and Hawkes investigate the death of a young man found in Central Park who died from an extreme allergic reaction and learn that he had been pretending to be someone that he wasn't.
