Sison sent Fidel Agcaoili to Japan to purchase an old 91-ton, 27.43 metres (90.0 ft) steel hulled fishing trawler which was known as the Kishi Maru.

[5] Victor Corpus, a defector from the Philippine military and a member of the NPA at the time, was tasked with leading the group that would receive the armaments at shore.

Believing they had been found by the Philippine military, the MV Karagatan crew moved their ship closer to the mouth of the Digoyo River.

The ship captain then started the engine, causing the MV Karagatan's hydraulic system to sustain damage after hitting a rock.

However the ship sank in the South China Sea on its way to Sanya Naval Base in Hainan, where the crew was to load hundreds of firearms concealed inside plastic tubes.

In the documentary, a crew led by Severino along with former NPA commander Victor Corpus went to Digoyo Point to visit the shipwreck of MV Karagatan.
