Lupin III: Harimao no Zaihou wo Oe!!

Lupin III is after the treasure of Harimao, a World War II-era thief whose collected loot has been lost for decades and is worth billions of dollars. In his pursuit, Lupin targets retired British spy Sir Archer, hoping to get the location of the treasure from him, but Archer unexpectedly joins the hunt. As a result, Lupin and Sir Archer must work together to outmaneuver a more formidable adversary who also seeks the treasure. Meanwhile, Inspector Zenigata is still hot on their trail.
