King, a trafficked lion cub, escapes from the airport in mid-transit and finds shelter in the home of Inès and Alex, 12 and 15. The siblings come up with a crazy scheme: to bring King back to Africa. Unfortunately, the customs agents on their tail don__APOS__t make their mission easier. But soon, Max, the kooky grandfather they__APOS__ve only met twice before, joins their adventure... and from then on, the sky__APOS__s the limit.
