The fourth film in the Lupin III animated series features master thief, Lupin in an adventure that revolves around his samurai sidekick Goemon. When Goemon's bride-to-be is kidnapped by ninjas from a rival family and Goemon's father-in-law refuses to pay the ransom, a priceless family vase, Lupin must race to save his friend's fiancee. All of Lupin's cinema and television capers traditionally end in a quest for a lost treasure, and The Fuma Conspiracy is no exception.
