Jodi Jones scored the 119th minute winner as Notts County came from two goals down to go through to the National League play-off final with a 3-2 win over Boreham Wood.
Notts were 2-0 down at the break and facing a desperate end to a wonderful season, but Aden Baldwin scored twice, including in the 97th minute to take it to extra-time after Ruben Rodrigues had missed a penalty for the Magpies.
As penalties were looming, Jones let fly from long-range and although Joe McDonnell got hands to it he could not keep it out and Notts had completed their comeback to book a place at Wembley.
