Shinichi and Ran's class decides to take a trip on a boat, but Shinichi decides against going. He quickly changes his mind when he finds a letter of challenge stating that one student will be kidnapped during the trip, more precisely, on a mean of transport. He is eager to accept the challenge. While they are on the plane, a student disappears.

Location: Plane
Victim: Maiko Tachibana
Suspects: Unknown

However, the teachers later receive a phone call saying that Tachibana has arrived at the hotel that they intend to stay at. On the other hand, Shinichi receives another letter from the kidnapper stating that Shinichi disappointed him and he will now abduct another student, on another mean of transport. Later, when they are returning from the dive spot on a ship, Sonoko is kidnapped.

Location: Ship
Victim: Sonoko Suzuki
Suspects: Shingo Kitajima, Mai Nishida, Kunio Azuma and Kyosuke Minamida

Shinichi soon receives a call from the kidnapper stating he will abduct yet another student at exactly twelve noon. The police announce that they will protect the students by having them gathering at the hotel's hall, with all the doors locked and guarded. However, at exactly 12 a.m., the lights suddenly go off. When they are turned back on, Ran has disappeared.

Location: Hall
Victim: Ran Mouri
Suspects: Shingo Kitajima, Mai Nishida, Kunio Azuma and Kyosuke Minamida

Shinichi receives a call from the kidnapper, who says that he has set up a bomb at where he keeps Ran and Sonoko. Kogoro, who arrived just before the incident, suspects Azuma, as he owns the ship on which Sonoko was kidnapped, and when Kogoro met him along with Nishida and Minamida at the hotel, Azuma suddenly left after receiving a phone call. Kogoro and Shinichi go to Azuma's house, only to find him dead.

Location: Azuma's house
Victim: Kunio Azuma
Cause of death: Hanging
Suspects: Shingo Kitajima, Mai Nishida and Kyosuke Minamida

Chief Tamagawa quickly arrives and informs Kogoro and Shinichi that Minamida is found dead at his house as well.

Location: Minamida's house
Victim: Kyosuke Minamida
Cause of death: Hanging
Suspects: Shingo Kitajima and Mai Nishida

Shinichi goes back to the ship to investigate. After looking at the closet in the room that Sonoko was sleeping at and Ran's camera, he realizes who is the culprit, as well as the trick to all three kidnapping cases. He then goes to the old harbor.
