Archaeologist and adventurer Oliana Molls is called by his former teacher, Dr. Jaume Tarruell, who commissioned him a secret mission: to locate "Bronze's Astlegleg", a trophy-shaped bronze statuette in which a human figure was delivered. At the beginning of the research, she allies herself with a daring post-teen, Betty Apricot, who is fascinated by the figure of her relative, Lord Sebastian Apricot, who discovers the astale. The English billionaire, before his death, had left a series of clues all over Catalonia that led to the trophy, the recovery of which he was to receive in his inheritance all the magnate's fortune as a reward. But this award attracts his two grandchildren, Charles and Robert, better known under the alias "The White Hands". In addition, there is the complication that Lord Apricot put forward a twenty-five-year term to locate the astale and make the reward effective; this is the last year.
