On a white-hot day in Tripoli, Libya, in the summer of 1979, nine-year-old Suleiman is shopping in the market square with his mother. His father is away on business - but Suleiman is sure he has just seen him, standing across the street in a pair of dark glasses. But whiy isn't he waving? And why doesn't he come over when he knows Suleiman's mother is falling apart?
Whispers and fears intensify around Suleiman: his best friend's father disappears and is next seen being interrogated on state television; a man parks his car outside the house every day and asks strange questions; and his mother frantically burns his father's books. As Suleiman begins to wonder whether his father has disappeared for good, it feels as if the wall of his home will break with the secrets that are being held within.
