When a family moves to the countryside, the children are reluctant to embrace their new lives until they discover an enchanted wood full of eccentric characters in this fantasy adventure film. Based on the book by Enid Blyton.

Timid nine year old Sasha teams up with his beloved family dog Charlie (voiced by Owen Wilson), who gets abducted by aliens and returns with superpowers, to thwart a plan by the neighbour's sinister cat Puddy to destroy humanity. Charlie is determined to fulfil his destiny and protect the ones he loves the most, only to learn that real heroism comes from courage, kindness, and believing in yourself.
