Aurora Mannindo, a 21-year old social work student, dreams of working with hospital patients in therapeutic care, but first she has to get through her final work placement at a homeless shelter for men. For Aurora, it's the placement from hell. Her days are filled with red tape and paperwork, and several of the clients - what the staff call "Red Flag Clients" - are overtly threatening. Two in particular, Marcus and David, seem to go out of their way to menace her. When her driver's license disappears the week Marcus is about to leave the shelter, Aurora begins to fear for her life. To save her best friend, Bianca, and her boyfriend, Carlos, Aurora is willing to fight to the death - but whose?
