Gibby's brother, Jason, won't speak of the war or of his time behind bars, but he wants a relationship with the younger brother he hasn't known for years. Determined to make that connection, he coaxes Gibby into a day at the lake with some older women. But the day turns ugly when they encounter a prison transfer bus on a stretch of empty road. One of the women taunts the prisoners, leading to a riot on the bus. The woman finds it funny in the moment, but is savagely murdered soon after. Given his violent history, suspicion turns first to Jason. But when the second woman is kidnapped, the police suspect Gibby, too. Determined to prove Jason innocent, Gibby must avoid the cops and dive deep into his brother's hidden life. What he discovers is a truth more disturbing than he ever could have imagined.
