The game's storyline revolves around a good-natured young girl named Laura as she solves the mystery of a magic diamond by helping the people around her.

One day, as she is admiring her grandfather's stone collection, Laura picks up a volcanic rock, but accidentally drops it and it shatters on the floor.

Laura's father, Anthony, is saddened after a small quarrel he had had with his wife which had caused her much grief and needs help to come up with the perfect way of asking forgiveness.

Tommy, Laura's younger brother, is crying because, after taking his father's binoculars without asking permission, he had forgotten them at the town gates and had disappeared when he had realized this and had gone back for them.

Laura's grandfather Henry, many years after his encounter with Lumina, is still saddened that people fail to believe his story and longs to one day have the proof it takes to convince everyone.

Rosie, the cook, is struggling to finish a crisp for the evening's celebration, but she had neglected to collect the nuts that Carmen the fruit merchant had saved for her and does not have time to go to town.

Outside, people, too, need help carrying out their daily tasks; Carmen, at the produce stand, has run out of mushrooms, Violet the florist needs her watering can re-filled, Theo the tramp needs a job and Mr. Morris the milkman's back is too painful to continue working and is in desperate need of an assistant.

The use of the space bar allows Laura to interact with human characters, open doors and drawers, climb up or down ladders and use the objects inside her backpack.

The bargain UK release from Focus Multimedia (with the British English dub), however, can be configured to be readable by Windows XP.
