Craig visits his dentist to have twelve teeth extracted. Craig's medical history form discloses that he is on blood thinning medication, something the dentist, Claire, is aware of.

The extractions are completed in one sitting and Craig is sent home with standard post-care instructions. Several hours later, Craig's brother, David, brings Craig into the dental surgery as his gums are bleeding profusely.

Claire advises Craig to bite down on some cotton wool and tells him that the bleeding will stop shortly. Craig faints due to the blood loss. An ambulance is called but doesn't arrive for over an hour. Craig dies in the dental waiting room. Later, the cause of death is confirmed as a heart attack brought about by blood loss.

David, haunted by the sight of watching his brother die, has recently been diagnosed with PTSD.
