Four years after Dumbledore's death, Draco Malfoy shows up on the doorstep of number twelve, Grimmauld Place looking for Harry Potter. Torn between his own self-preservation and his family's pride, Draco finds himself alone on a battlefield and has nowhere else to turn; and Harry has to learn that sometimes you don't put up walls to keep other people out, but to see who cares enough to break them down.

After the Battle of Hogwarts, all students were asked to return to repeat their year for a proper education, much unlike what they received the previous year with Death Eaters as professors. After Draco helps Harry calm down after a panic attack, they quickly learn that mental and physical changes (such as Draco's dyed blue hair) were not the only changes that took place, but emotional ones as well.
