Here is the description that came with the video:
The woman in the video found the lion, injured in the forest, on the verge of death. She took the lion home with her and nursed it back to health. Later, when the lion was better, she made arrangements with a zoo to take the lion. Some time passed before the woman had a chance to visit the zoo. This video was taken when she walked up to the lion's cage to see how he was doing. Watch the lion's reaction when he sees her!!
