A casino employee is beaten and raped on her way home from work, but she survives and identifies her attacker. Unfortunately, a DNA test sets him free and Grissom must wrestle with whether evidence can ever lie. Later, Grissom comes to the rescue of a coworker who ends up on the other side of the law

The team searches for a mother and her two children, who are last seen boarding a yacht which is later found adrift in New York's Harbor with only its dead captain aboard. Meanwhile, Malone gets ready to leave the team and move with his family to Chicago.

From nutty diets to expensive facial creams that don't do anything, the magicians blow apart the efforts by those who are living longer than ever to turn back the clock, whether they are lining up for Botox injections or extensive plastic surgery.
