His brother-in-law, CJ Macias, meanwhile, gets back on a board after recovering from his own significant accident, while Chumbo reflects on his surfing priorities now that he's a father. Just after Justine and Tony make a difficult decision about their partnership, a tragedy of the highest magnitude strikes Nazaré.
