Four friends break into an abandoned insane asylum in search of a death certificate which will grant one of them a large inheritance. However, finding it soon becomes the least of their worries in a place haunted by dark memories.

Cass is the story of a middle class family in Detroit - a single father, his fifteen-year old daughter and eleven-year old son - whose lives are changed when a mysterious artist takes up residence in the abandoned building next door. From the brilliant murals of the Diego Rivera courtyard to the hollowed-eyed homes in Detroit neighborhoods, the film explores issues of passion - of what and who we long for - as well as the secrets we keep to protect ourselves and the ones we love.
