This fantasy film is an adaptation of the legendary stage musical “Cats”, composed by Andrew Lloyd Webber and also based on the T.S. Eliot’s collection of poems "Old Possum's Book of Practical Cats.” In the focus of the story are the Jellicles - a tribe of cats, each of them with its own strong individuality and amusing name. The Old Deuteronomy (Judi Dench), Macavity (Idris Elba), Bombalurina (Taylor Swift), Jannyanydots ( Rebel Wilson), The Old Theatre Cat (Ian McKellen), and their feline peers gather for a very important meeting. Every year they come together to make "the Jellicle choice" and take a decision which of them will ascend to the Heaviside Layer, one of several layers in the ionosphere of planet Earth. The furry creatures believe that whichever of the Jellicle cats is the chosen one, she or he will come back to a new life after this ascending.
