Guidé par un rêve, Yakari part rendre visite aux Indiens du nord, grands spécialistes de la pêche. Mais une orque redoutable complique terriblement la vie de ces derniers. Yakari est leur seul espoir de pouvoir communiquer avec le cétacé.
The Beavers are very worried: Linden Tree, Yakari’s yound and
mischievous friend, has lost his appetite for … well, everything. And
his people have no time to devote to him, as they must repair their
precious dam, damaged by heavy rains. While the young Sioux attempts
to dispel his friend’s melancholy, Thousand-mouths suddenly realises
he is several labourers short of a full work gang. Is something in
the lake going after the hard-working beavers?
