The air of positivity that had swept over the Memorial Stadium following a half of football that saw the home side deservedly lead 2-0 was refreshing for the beleaguered manager, whose side had not won in five league games. The two goals Argyle had scored after 79 minutes meant the green army finally had the Christmas cheer that has been such a long time coming, the stoppage-time winner wrapping up the relegation battler's perfect present.
The seasonal good will was not extended to the under-fire Rovers boss, who was jeered off the pitch by the frustrated locals growing increasingly weary of their supposed promotion push being thrown to the dogs in post-dinner scraps.
The bad feeling towards Buckle has been reinforced by his egotistical nature; club legend Stuart Campbell agreed to a contract termination last week, after the pair played out a war of words through the local press - striker Jo Kuffour has also been shown the door during the opening months of 41 year old's turbulent reign.
The result resurfaced uncomfortable memories for the Rovers faithful. In the opening week of 2011 the Pilgrims visited Bristol, finding themselves 2-0 down after just 11 minutes, but three second half goals sent the Greens home with the points. Only one of the Argyle players from that game took to the pitch on Monday, yet the end result was just the same.
With the first half an even affair, Rovers made the first great opening of the game, Andy Dorman's header forcing Jake Cole into an athletic save, pushing the ball onto the woodwork to keep the game level.
He had little chance to keep out the opener, however, the Pirates' top scorer Matt Harrold converting the penalty he won after a trip from Onismor Bhasera.
Harrold's second, his tenth of the season, completed a two minute double-salvo, Joe Anyinsah's tinsel-toes evading Bhasera's challenge before his cross found the well-travelled striker. Rovers were making it a blue and white Christmas.
As home supporters wandered off for a half-time pasty, they were looking upwards - towards seventeenth place, no less. Argyle, meanwhile, were left at the foot of the table; a quirk of the day's results leaving them in that position, thanks to Dagenham's 3-0 win over Barnet.
The full effects of the previous days Christmas lunches appeared to take it's toll on the Rovers' players as the second half commenced, Plymouth clawing a goal back through Warren Feeney. The Northern Irishman forced the ball past Scott Bevan after Nick Chadwick had knocked down Ashley Hemmings corner in the 52nd minute.
Andy Dorman's volley was thwarted by Cole at one end, before Chris Zebroski was forced to clear off the line at the other. Though before long, the Pilgrims got the equaliser their efforts, or Rovers' lack of, deserved.
Plymouth's momentum was pegging back the home team into their final third, the pressure only relenting when Chadwick shrugged off Eliot Richards and struck a fierce drive past Bevan to level the scores.
The Greens were carving Rovers apart and, with the home side wilting with fatigue, any joy was destined to head to Devon.
Bevan's sharp reactions kept a Chadwick header from flying under the crossbar but, soon enough, the former Torquay stopper's mark out of ten went down the chimney. A poor clearance found the grateful feet of Hemmings, whose pace allowed him to go one-on-one with the lanky goalkeeper, his cool finish defying the Wolves loanee's lack of senior experience.
The rapturous scenes in the away end continued right up until the final whistle; the Plymouth entourage driving home for Christmas with all three points. The Rovers faithful hoping the only trip Paul Buckle was taking went straight to the North Pole.
