A storming second half guided Slaughtneil once again to the senior county title and their eighth time in-a-row lifting the Father Collins Cup.
Top scorer Cormac O'Doherty lifted the trophy after the game in which his side ran out 12-point victors.
Celtic Park welcomed the two best teams in this year's championship and provided the canvas for Slaughtneil and Kevin Lynch's to write the latest chapter in their fierce recent rivalry.
Backed by a vicious wind Kevin Lynch's took the bull by the horns and raced to an early 0-6 to one point lead by the end of the first quarter.
Free-taker Eoghan Cassidy notched five of those six scores, the best a clinker from play in the 12th minute.
Trailing by four at the water break, Slaughtneil reversed the momentum of the contest for the remainder of the first half.
The 18-year-old Shea Cassidy was a surprise starter for the holders, but the youngster repaid manager Michael McShane's faith in him with a sprightly display in the first half. Cassidy's point in the 17th minute was the first of six consecutive scores as the champions whittled away at their deficit before Cormac O'Doherty's third free edged his side ahead for the first time on the cusp of half-time.
Kevin Lynch's, so impressive in their opening salvos, all but shot themselves in the foot amassing 11 first half wides and in doing so let their more clinical opponents of the hook.
As the half wore on Slaughtneil's leaders - Chrissy McKaigue, Cormac O'Doherty and Brendan Rogers - found some element of control and possession. Scores soon followed.
A late Darragh McGilligan point brought parity to the scoreboard as the referee blew for half-time.
Two quick scores from Niall Ferris, the second of which from an improbable angle, edged the underdogs ahead early in the second half. The Emmet's responded and by the 38th minute the sides were level again. And after that Slaughtneil took complete charge, accounting for 14 of the next 15 points.
For a man who failed to score until the 26th minute, Cormac O'Doherty would eventually boast 12 points to his name including the final point of the game, a free hit from his own half.
Slaughtneil win, again.
