Off the coasts of Papua New Guinea and the Solomon Islands, the wrecks of Japanese and Allied ships from World War Two sit largely undisturbed, some still loaded with ammunition and guns now colonized by tropical fish. Diver and filmmaker Ben Cropp takes an underwater HD camera through these silent decks, then moves onshore to jungle sites where crashed planes and gun emplacements have been swallowed by sixty years of foliage. Cropp treats each wreck and relic as a memorial rather than a curiosity, tracing how the fighting in these waters brought the war within striking distance of Australia itself. He talks with people whose lives were shaped by that threat, including those who stayed home while the fighting raged offshore, giving the underwater footage a personal frame rather than a purely archaeological one. The film moves between reef and rainforest, letting the rusted hardware and overgrown wreckage stand as physical evidence of a campaign that could easily have reached Australian shores.
