Jim and Alison are on a special mission to Cancun in Mexico. They have travelled 5,000 miles to collect a lively three-year-old chimp called Bryan, who has been mistreated by his owner and needs a home with his own kind. Jim and Alison must prepare Bryan for the long and difficult journey back to Dorset. Meanwhile, Alison is frustrated in her efforts to rescue an adult chimp named Coco, who belongs to the same owner.
