Shawn, Gus and Henry look into the death of a woman from 20 years ago on the season finale of Psych.

When the body of an influential Santa Barbara business man is found at a construction site, his body isn’t the only one found at the site. When the second body is identified as Veronica Towne, a waitress who went missing twenty years ago, the case gets reopened and Henry rejoins the force as a detective to finish what he and his former partner started.

As a result of the case and the realization that his co-workers weren’t as clean as he thought they were, Henry decides to step down and finally retire.

When Henry goes to tell one of the few men left from his team, he gets more than he bargained for when it becomes evident that he was in on it as well.

Unfortunately for Henry, this realization ends with a potentially fatal confrontation.
