When a tourist is found dead in Central Park with the word 'guilty' written across her forehead, Detectives Olivia Benson and Elliot Stabler recover photos from the victim's camera. With the help of crime scene unit technician Dale Stuckey, they discover that former artist Peter Harrison was at the park during the crime. After arresting Harrison for questioning, the detectives leave Detectives John Munch and Fin Tutuola to keep Harrison under close surveillance. But when Harrison suddenly escapes, Detective Munch must turn to his ex-wife Gwen for help.
