Part one of two. After receiving hundreds of hacked messages from a murder-for-hire online site, true-crime obsessive Yinka Bokinni journeys deep inside the dark web to find out if it's possible to anonymously order someone's death. The hacked message shows hundreds of people all over the world have been ordering hits online. This isn't gangland score-settling, either, but seemingly ordinary people who want friends, partners, work colleagues dead.

Part two of two. Yinka identifies a target from hacked messages in New York State, and tracks him down to see if he's still in danger and if she can help work out who's behind the proposed hit.
