In an accident, the introverted brother David (Tobey Maguire) and the hot sister Jennifer (Reese Witherspoon) came to a black and white world: Happy Valley. This is exactly the TV scene that David has loved for a long time: there is no color, and people live a peaceful life without waves and thrills. The lives of the residents are like a set of established procedures, and every day is well-behaved without any accidents. The couple respects each other, the children are well-behaved and obedient, there is no basketball that cannot be thrown into the basket, no books with stories, and no late dinner. The arrival of the brothers and sisters gradually changed this black and white world. Especially under Jennifer's passionate and unrestrained personality, people began to be surprised to find that they actually saw colors. Colors spread in Happy Valley, and the visible people were attacked by invisible people. Conservatives cannot accept the appearance of color and cannot see people opening the Pandora's box of desire and instinct. However, Happy Valley is still vigorously promoting the color wave.
