In de toekomst bestaat er een virtuele wereld genaamd Wonderland. Het is een plek waar kunstmatige intelligentie mensen nabootst die overleden zijn, zodat ze herenigd kunnen worden met mensen die hen nooit meer zullen zien. Zo wil een jonge vrouw haar vriend weer ontmoeten, die door een ongeluk in coma is geraakt, en tracht een man van in de veertig zijn overleden vrouw weer te zien.
