Liv isn't happy with the perfectionist brain that she eats to solve the murder of a gourmet chef. Clive pays Michelle a visit at the hospital, Major tries to find the traitor within Fillmore-Graves, and Ravi helps Charlie bond with her twin sister.

Liv tries to look out for Martin and deal with Evan's medical problems, while working on a case with Clive about a beauty-queen contestant who was given spiked makeup, went into anaphylactic shock 20 years ago, and recently died. Major searches for the missing Sloane, and Ravi and Peyton track down Beanpole Bob.
