LOGLINE:
A killer targets Shawn using scenarios from classic Hitchcock films.

SYNOPSIS:
Shawn arrives late to meet Gus at a screening of Psycho, and has to squeeze down the row past other theatergoers to take his seat. On their way out of the theater, they are surprised to meet Mary Lightly, who helped them track serial killer Mr. Yang. Mary takes them to a diner, where they discuss Yang's new book that has just been released. Mary points out that, according to the book, Yang could not have been working alone. She had an accomplice. Shawn and Gus don't believe it, and leave the diner – and the Yang case – behind. But later they are called to a crime scene to find the waitress from the diner murdered and her body arranged into a Yin/Yang symbol.

Shawn, Gus and the cops meet Mary at the diner where they find a Yin/Yang symbol on a pie and a crossword clue inside of it, daring them to "Find Me." Mary says this is the work of Yang's accomplice, Yin, so Shawn, Gus and Mary go to talk to Yang in jail. Yang tells them that she did have a partner, and Yin is worse than she is. Lassiter calls and tells them that the same of the person who wrote the crossword is Ben McKenna, a name Gus recognizes as a character in the Hitchcock film The Man Who Knew Too Much. Shawn takes them back to the theater where they saw Psycho earlier, and uses the crossword clues to find a seat, in the same row they sat in the night before. Shawn remembers squeezing down the row, but not the face of the person sitting in that seat. Juliet finds a taunting note under the seat. Mary says Yin is acting alone now, and being the opposite of Yang, has no rules. Gus suggests going with the Hitchcock theme and reviewing all of his movies. They all split up an Shawn falls asleep in the middle of his film. But as he dreams, he remembers the person in the theater seat to be Mary. Mary is Yin.
