Lupin breaks into a prison and frees a strange looking man he knows from previous heists. When the strange man questions what Lupin plans on doing with him, Lupin begins to talk about a hidden "safe trunk" containing millions. Lupin proposes an offer to split it 50-50 if he helps him get the trunk, an offer the man readily agrees to. But Zenigata is on Lupin's tail. Who is this man, and will he really agree to help Lupin? Will Jigen and company come to help? Will Zenigata finally catch Lupin?
