S4·E21 The Unblinking Eye

After a young actress is gunned down after an evening out with her boyfriend, Goren and Eames initially focus their attention on a young man who had showed an unusual interest in the couple, but soon realise that there is more to this case than meets the eye. A jealous and seemingly obsessive ex-girlfriend, a best friend who never made it as an actor, and a grieving boyfriend who seems too good to be true lead Goren and Eames down another path, one where the key to exposing the truth about the present depends on exposing the lies of the past.
