The story is about a woman Laura who took over the house which used to be the orphanage she lived in as a child. Her adopted young son Simon is HIV positive and has a habit of making imaginary friends and starts to make new imaginary friends in this house. Through a series of item hunting game which his imaginery friends taught him, he realises that he is adopted.
During a party at their new house, Simon argues with Laura and he goes missing. Everyone believed Simon to be dead, but Laura insisted that he is still in the house.
The story ends when Laura discovers, through a medium, that a boy was bullied and accidentally killed by some children of the orphanage. The mother of the bullied boy had killed the children and stored their bones and ashes in sacks hidden inside the coal storage outside the house.
Laura's husband leaves the house and Laura promises him that she will be done in two days. Laura recreates the original orphanage layout and attempts to contact the ghost children, who leads her to Simon. She tells Simon to close his eyes and pretend to go to sleep, so that when he opens his eyes again, they will be back to normal, like when they have just moved in. Simon obediently closes his eyes and the ghost children vanished. Laura then realises that there is nothing in the blanket. She then sees Simon's body at the bottom of the stairs. This scene is so sad and is the highlight of the show, because you really thought it was all the act of the ghosts and Simon is not dead, though you feel like something is not right but you just can't put your finger to it. Then as you follow the show, you understand and can feel Laura when she realises that Simon is dead.
Laura starts to recall that on the day of the party, she had accidentally blocked the hidden door to the basement where he was playing, trapping him inside, and that the unexplained noises she had heard were Simón trying to get out. At one point she had heard a loud crash which had been Simon falling through the stair railing, and onto the ground below, breaking his neck. Laura then realizes that she had inadvertently caused Simón's death.
Heart broken, she carries Simon's body up to the bedroom where the orphans had slept in long ago. She started to take mouthfuls of pills which resulted in her losing consiousness (and then death). When she opened her eyes next, Simon is alive and opened his eyes as well. Simon then tells Laura that his wish was for her to stay and take care of all the orphans. All the other orphans start appearing infront of Laura. While this was haunting when the children started appearing, it gets abit sad, when you realise that they do not look ghostly, but really innocent young orphans who yearn for a mother, and Laura, out of her love for Simon, agrees to stay in this ghostly world to take care of all of them.
The movie then ends with Carlos walking alone over to the memorial for Laura, Simón, and the orphans which stand outside the house. Carlos returns to the orphans' old bedroom and finds a medallion, that he had given to Laura previously. He hears the door opening; as he looks up he slowly smiles.
