88 capuchins rescued from a research laboratory in Chile wake up to their first morning at Monkey World. In the Chimp nursery, Rodders has a run-in with a sticky melon, and Seamus comes face to face with alpha Butch in the bachelor pad.

Chimps Ben and Pip need to be sedated for their move from the nursery to Hananya's group, but they give vet John Lewis the run around. Alison is worried about how the rescued male capuchins will react when they are moved in together.

The team is forced to step in when the chimp introduction goes wrong and Ben is injured by the alpha male. Orang-utan Hsiao-Quai struggles with her ever-growing son Kai. The staff prepare to welcome another baby orang-utan into the fold.

Hananya shows that he isn't so tough when it comes to needles. The other chimps enjoy some 'banana-fishing'. Alison and Jeremy are in Hertfordshire to re-home two more capuchins, and there's an exciting development among the gibbons.
