When Tuft, a young Finder of Silverthorn Forest, wakes early from hibernation, he decides to set out on an adventure to find the legendary Faraway Forest. After an unexpected trip to London via a postbox, Tuft is reunited with his human friend Max, and secretly signs him up for an adventure camp in the New Forest. Tuft is convinced that they'll uncover the homeland of the Finders here, but Max is sceptical. The camp is the last place he wants to be spending his school holiday, especially as he doesn't have any of the right equipment and it won't stop raining.

But with a severe storm approaching, things soon turn perilous, and Max must use all of his newfound skills if he's to save Tuft and the new Finders they have befriended.
