The follow-up concerns, among other things, the new investigations into Estonia's wrecks.

- In two new parts, we follow the public conversation and the government's response in the aftermath of the documentary, revisit key people, meet new sources and follow the investigations that have been carried out, says the author Henrik Evertsson in a press release.

Both were praised and accused of spreading lies

It was two years ago that the documentary series revealed a hole in the hull of Estonia, which led the government to decide on new dives and Evertsson was awarded the Grand Journalist Prize.

Elsewhere, he was accused of spreading lies and conspiracy theories and he was named this year's deceiver by the association Vetenskap och Folkbildning.

The film production's dives at the wreck also led to an indictment against Evertsson for breach of peace.
