The Lesson

When Pamela Tripp's favorite uncle dies, she attends the viewing with her stoned-artist boyfriend, Kevin. After an altercation with her disapproving mother, Pamela can't leave the funeral home soon enough. Before she heads home, however, she needs to use the restroom. En route to the ladies room, she plucks a bloom from an expensive floral display, resulting in a harsh reprimand from one of the morticians.
 He sends her to use the restroom in the basement, which is being remodeled, and issues a warning to be careful and not wander around. But a 'Caution' sign on a locked door catches Kevin's eye and captures his attention. In spite of Pamela's protests, Kevin breaks in the door, grabs her hand, and takes her on a frightening journey she will never forget.
