Rachel has recurring
nightmares about her mother Eva being shot, which connects to a past incident where Eva was accidentally wounded during a police standoff involving Richard and a criminal named J.T. Morono. While Rachel struggles with the truth, Richard and Conan become involved in a string of attacks start with Inspector Meguire, Eva, Richard's wife and Dr. Agasa and linked to playing cards left at crime scenes. The case intensifies when friends and acquaintances of Richard—including golfer Henry Tish, sommelier Kevin Simms, and
businessman Christopher Aston—are targeted. At the AquaCrystal complex, several murders occur, each tied to the spade suit. Suspicion initially falls on Morono, but Conan deduces the real killer is
Kevin Simms, who faked being a victim. Kevin’s motive stems from losing his sense of taste after an accident caused by Nina Oliver and his resentment toward others in his circle. Using bombs and staged traps, he attempts to eliminate his targets and escape, but his plan collapses. Richard subdues him, ensuring he faces justice. In the aftermath, Rachel reconciles with Richard, realizing his actions years earlier were to protect her mother. A final scene reveals Eva left Richard not over the hostage incident, but because of his harsh criticism of her cooking.
Playing card symbols During the course of the film multiple characters are represented by a certain number from a standard deck of cards. The playing cards are all spades, which represents death. The victim's name, clue left behind, and the connection with the number are all displayed below in the chart. Since the English adaptation has changed names of the characters, the corresponding relationships between the character and the numbers were changed accordingly. == Inspiration ==
