Dexter has always known his father's Code was meant to protect him from exposure.
But after committing a serious mistake, he wonders if it could have been designed to
protect him from something even more dangerous - human emotion. When he discovers that
Trinity is planning an out-of-town trip, Dexter sees an opportunity to ride along and gain
insight into the mind of a fellow monster. Even so, Dexter isn't prepared for the
startling revelations Trinity makes along the way, revelations about his own past which
only serve to convince Dexter of what he must do. Meanwhile, back at Miami Metro, Debra
refuses to let a technicality keep her off the Trinity case. She works through others to
ensure her voice is heard - that is, until she realizes that her single-minded pursuit of
the Trinity Killer may have blinded her to the truth.
