A one-act play about a brother and sister, Michael and Michelle, who are trying to make sense of their dysfunctional childhood.
The central narrative involves Michael finding a baby, who he names Debris, and how he tries to keep him from his alcoholic father.
He confides only in Michelle, who remains fascinated by their mother's death, and gives several contradicting stories of how she died.
Kelly has said "I was brought up a Catholic, so, like every decent Catholic, as a child I fantasised about being crucified - it must have come from there"[2] Kelly original had problems getting Debris produced until approaching Theatre 503 "The play had been rejected by pretty much every other theatre around but 503 saw something in the play and decided to abandon common sense and produce it.
For me it was one of the most important moments in my life"[3] Debris was developed whilst Kelly was on attachment at the National Theatre Studio.
