Substitute Kieran Brannon made an immediate impact with a late equaliser to earn Annan a 2-2 draw at Stenhousemuir.
Annan struck the first blow in the 26th minute when defender Martin McNiff fired home.
The League Two outfit held the lead until five minutes into the second half when Darren Smith played in Errol Douglas, who stroked the ball home.
John Gemmell turned the game on its head seven minutes later as he curled his right-footed shot into the top corner.
But there was plenty of time for another twist and Brannan delivered it with one of his first touches to take the tie back to Galabank.
