Lupin the Third: The Secret of Twilight Gemini

“The Twilight Diamond's rock-solid secret is about to be cracked!”

It starts at a deathbed, where Lupin's old mentor Don Dolune presses a diamond called Twilight into the master thief's hands. It is only half of the treasure, and the other half is somewhere in Morocco. Gisaburō Sugii sends Lupin (Kanichi Kurita) after it with Fujiko, the mysterious Lara and a whip-wielding maniac all in his way, and he never stops to decide which of them he should trust.
