Kaleido Ghost

Vivienne, age 9, returns to her old English neighborhood. After two years in the USA, she's eager to reconnect with the familiar surroundings of her childhood. On a trip to the local playground with her mother, Heidi, Vivienne spots a group of five kids she remembers- they're eerily dressed in Victorian clothing. As Vivienne joyfully rejoins her spectral playmates, her mum remains unaware, chalking it up to vivid imagination while she waits at the roadside. But when a mysterious golden kaleidoscope appears, the boundary between past and present begins to blur. - IMDb
