The inside story on one of the deadliest gang wars in the history of the State will be told in a TV3 documentary tonight.
The feud between the Kinahan cartel and the Hutch gang has resulted in seven deaths this year, and shows no sign of ending any time soon.
The feud began when Gerry 'The Monk' Hutch's nephew, Gary Hutch, was gunned down by a poolside on the Costa del Sol last September.
However, it spiralled out of control when a team of six hitmen stormed the Regency Hotel in Dublin - some of them dressed as members of a garda Emergency Response Unit and carrying AK47 assault rifles - and gunned down a member of the Kinahan gang, David Byrne.
The programme explains why the murder of Byrne was the pivotal event and led to savage recriminations.
The mounting body count is happening against a backdrop of a more reckless and ruthless crime scene that is engulfing the capital.
The documentary will hear from Herald crime correspondent Ken Foy and other journalists who have followed events closely.
Garda Chief Superintendent Michael O'Sullivan of the National Drug Unit and Organised Crime Unit will be interviewed on the programme, along with former head of the Criminal Assets Bureau Felix McKenna.
Dublin's Gangland War airs at 9pm.
