The murder of a kid in a NY park leads our CSIs to meet the mob's next generation of "made" guys from the Tanglewood section of the Bronx, only these not-so goodfellas kill for sport instead of business. Mac and Stella discover the murder of a convenience store clerk was committed by a wannabe who was trying to impress other Tanglewood gang members. The death of a female driver in a hit and run accident leads Danny and Aiden into the backrooms of an Asian massage parlor, where the woman was a masseuse and the evidence indicates one of her male clients may have been unhappy with her.
