Detective Conan of long-running manga and anime fame returns for his 23rd feature film – even beating Avengers: Endgame at the Japanese box office! When Conan’s friends travel to Singapore, he’s forced to stay back in Japan because he doesn’t have a passport. But there’s no rest for this detective, as he’s transported to Singapore against his will by his nemesis, the charismatic thief Kaitō Kid. He has the ability to transform his appearance into anyone – including Conan – and poses as him to fool Conan’s friends, who are none the wiser.
The two begrudgingly agree on a temporary truce and soon find themselves embroiled in a case involving a martial arts tournament and a mysterious blue sapphire. Kaitō Kid has big plans to steal the sapphire but is shocked when someone else gets there first and frames him for the crime. When Kaitō Kid goes on the run, suddenly Conan’s lack of a passport is the least of his problems!
