No Stone Unturned is a feature length film which over the course of an hour and 50 minutes deeply examines the unsolved 1994 Loughinisland massacre which occurred in Loughinisland, Co. Down, Northern Ireland during the troubles.

It was a vicious shooting which claimed the lives of six innocent Irishmen as they watched the World Cup, presumably the shooting was carried out by a Unionist paramilitary group.

We see filmmaker Alex Gibney reopen the mysterious case and gradually reveal a string of evidence which points towards several perpetrators who were never charged with the crime due to what appears to be collusion.
