3x4 - Lupin the Third

Deep beneath the whirlpools of the Bermuda Triangle, Lupin and Jigen discover a pirate ship containing tons of Spanish gold. Before the two can collect it, a submarine manned by a team of female pirates intervenes. After a quick skirmish, Lupin and Jigen escape empty-handed, as do the pirates who cannot get past the whirlpools to reach the gold. Later that evening, Fujiko is kidnapped right before Lupin's eyes. The Captain informs him that if he wants to see Fujiko again he must steal the gold for them. Will the pirates hold up their end of the bargain? And whose voice is Lupin hearing in his head?
