I figli di Sam: verso le tenebre

I loved this short series. I wasn't sure what to expect but couldn't turn it off - it gives a fascinating insight into a journalistic investigator whose interest and work led him to obsession. At every turn in trying to seek the truth he's faced with deaths or obstruction. The documentary lays out his theory, developed over decades, that there is something far more sinister at play. Whether you shrug this off as conspiracy theory or find his cobweb of evidence & theories plausible, his dogged determination and lifelong obsession makes compelling viewing.
