The Clades, a family of legendary explorers, discover an unexplored world, full of dangers and populated by fantastic creatures.

Alas, the quarrels between its various members threaten to derail this new mission, which is – by far – the most crucial.
This new Disney feature film canned by the dads of Big Hero 6 and Raya is obviously technically impeccable, and approaches via its uchronic-fantastico-SF universe the pulp adventure genre.
