Joe Washington is a down-to-earth blue-collar plumber, traveling between old city pipes day after day.However, one night after his father passed away, he unexpectedly discovered that the old man who was always silent in his memory was hiding a dark wall covered with newspaper clippings and passwords.When the debt-debt gunfire broke the silence of the rental house, and when the blood-stained cowhide envelope slid out of the ventilation duct, Qiao was shocked to realize the shocking lie that his father woven during his lifetime - the "suicide scene" that took the blame for others, the millions of dollars disguised as pensions were all abandoned in a deadly chess game. When the debt collector's bullet rubbed through the convenience store glass, Qiao saw the gesture of his mother tremblingly taking out the riot spray; when the young man pulled open his greasy work clothes and exposed his tactical belt, he remembered the joke that "the son of a veteran of Vietnam War always had to prepare for war."Now in this shabby RV carrying the whole family to escape, the on-board radio is still playing weather forecasts, and the windshield reflects the ultimate puzzle left by seven ordinary people redefined by death, driving towards their father in the twilight of the highway.
