Once Upon A Time In Africa

Grandma Rose and grandpa Jeff are out for a stroll when the churchbell chimes and shrinks grandma with every strike. She disappears and reappears in an African national park as a lioness, where, with a computer, the animals have summoned her for their annual play staged for the visitors of the park in which she is the protagonist. She lives in a camp and rehearses her part. She meets other animals as well as the park rangers who all live to entertain the tourists.
At the end of the season, the computer returns her to grandpa Jeff.
