Neal Caffrey has no alibi for the robbery from a Manhattan fashion house's safe of the world's largest pink diamond, which was replaced by a masked man resembling him with a synthetic one bearing his initials. Peter Burke has nothing to prevent Neal being jailed by a hostile agent from OPR, the FBI's internal affairs branch. Neal however escapes, helped only by Mozzie, 'hides' at the Burke home invited by Elisabeth and sets out to prove the only other logical suspect, Tumblane, faked his alibi and was hired by a third party.
