Plot

The Seal

Professor Agasa, Haibara, Conan, Ayumi, Mitsuhiko, and Genta go camping. While they're camping they find a lantern in a pond with some writing inside. They show the stone lantern to Conan who determines that it is a code to finding a large diamond. The lantern is also hiding another secret...a dead body at the bottom of the pond.

Murder
	Victim: Teruhisa Tamai Cause of death: Strangulation

After searching the body they find out that he was a treasure hunter who was straggled to death by another person looking for the treasure. They also find a tear-shaped stone with the kanji "inflammation" written on it and a notebook. The notebook suggests that he was murdered by his partner and that Kaitou Kid is also seeking the treasure. Dr. Agasa goes back to camp to call the police.

The Mechanism

Conan, Haibara, and the kids decide to enter the house which belonged to Kichiemon a puppet maker and architect of the riddle. The house is filled with all kinds of booby-traps which Genta almost falls victim too until another treasure hunter saves him from a pit of spikes. As they continue to search the house they meet another treasure hunter, and end up falling down a trap door into the basement. Luckily they are saved by Conan's supersized soccerball. In the basement they find Kichiemon's grave, a bunch of human remains, and an old lady. The first treasure hunter reveals grudgingly that he found the mirror artifact and Conan reveals the tear-shaped stone. They continue looking for the sword, which is the last piece of the puzzle.

The Resolution

The old lady nearly gets chopped up by four swinging blades when she steps on a trap. Conan realizes that if one stands in the right spot the blades will not harm you and that one of the blades actually has a handle allowing him to swing over towards the sword. The sword contains the last clue, which leads everyone back to the pond.

Resolution

  Show spoilers »

Mitsuhiko accidentally discovers that the diamond is at the bottom of the pond. The first treasure hunter dives in after it while the second pulls a gun planning to kill everyone and take the diamond for herself. Conan is able to tranquilizer her, but when the treasure hunter comes back up with the diamond the spring starts to pour into the pond causing a massive flood. The only way to stop the flood is to put the diamond back. The old lady turns out to be Kaitou Kid who knew all along that the diamond was unable to be stolen, and Conan allows him to escape on his hang-glider. But the diamond maybe on a weight-based or shape-based mechanism most likely the former so chances are you CAN steal the diamond if you can figure out the shape, weight and dimensions of said diamond and replace it.

Remastered versions
