n Tokyo - one of the world's largest megacities - a stray cat is wending her way through the back alleys. And, with each detour, she brushes up against the seemingly disparate lives of the city-dwellers, connecting them in unexpected ways.

But the city is changing. As it does, it pushes her to the margins where she chances upon a series of apparent strangers - from a homeless man squatting in an abandoned hotel, to a shut-in hermit afraid to leave his house, to a convenience store worker searching for love. The cat orbits Tokyo's denizens, drawing them ever closer.
