It's now summer, and Charlie and Fred find out just how tough life on the river can be when they take possession of an injured baby kingfisher.

Charlie tracks down some new otters on the river - a mum and a cub - and takes five-year-old Gus out to try to film them.

Philippa enlists the help of a hundred and fifty thousand new bees to try and help the native riverside flowers but, to her disappointment, they're only interested in the non-native ones. So she decides it's time for action.

At the aquarium, the boys get a glimpse of a rarely-seen underwater predator, the voracious dragonfly larvae.

And conservationist Philippa is keen to protect the small population of water voles on the river by trapping the mink. So the family joins a group of like-minded volunteers and builds a flotilla of rafts, which will hopefully detect any of the passing predators.
