In Plain Sight - Part 1

Ashley Coulston was an adventurer - someone who craved attention and fame. For a brief moment, he was famous - making headlines after an ill-fated attempt to sail a bath-tub sized boat from Australia to New Zealand. But these days, Coulston’s infamy has eclipsed that short lived fame. Michael Usher leads a special investigation that reveals why Coulston may go down as Australia’s worst ever serial killer and rapist.
