By chance, the dull-witted Noah (Chris O'Neill) and his quirky sister Emma (Rhiannon Leigh Wryn) found a mysterious box on the beach. In the box, they found many unprecedented "toys" and a toy rabbit that could communicate with them. These magical discoveries gave Noah and Emma many special abilities that natural science could not explain. Joe (Joely Richardson) discovered the abnormality of her two children, but no one, including her husband David (Timothy Hutton), believed what she said. Agent Broadman (Michael Clarke Duncan) of the Department of Homeland Security took away the mysterious box, and the children and the toy rabbit were forced to separate. Seeing that the life breath of the toy rabbit was getting weaker and weaker, could Noah and Emma save it from danger?
