Dutch Courage - S4.E9

There is something strange about the suspected foreign fishing vessel that a crew from Hammersley boards in the Timor Sea. On the deck are four Australian men who claim to be on a fishing trip, but Dutchy is suspicious of a fishing boat that seems to be carrying no bait, no nets, no fish and without any "blood and guts" on the deck. Further investigation reveals a cargo of illicit alcohol — and results in the XO being held hostage with a machete at her throat while the rest of her crew is sent packing.
