Imagine coming home one day to find in your room... a lion. Scary, isn't it? Even though that's exactly what happens to the main character of this film, 12-year-old Inessa, she doesn't get scared. Well, to be fair, it's not a full-grown lion, but a very young lion. The animal was transported by plane by poachers hoping to sell it for a profit, but the lion managed to escape and hide in Inessa's house. A kind-hearted girl, she immediately falls in love with the little lion and decides to bring it back to where it belongs - home, in Africa. Naming him King, Inessa sets off on an adventurous mission to rescue the lion with her brother and grandfather.
