Jon Main scored a late penalty to earn Blue Square Premier new-boys AFC Wimbledon a draw from their opening-day clash with relegated Luton.
The Dons substitute picked himself up to fire into the bottom corner with 10 minutes left after being brought down by Shane Blackett, who was sent off.
Luton had earlier begun life in the non-league by taking an early lead.
Tom Craddock blasted them in front from the spot in the 14th minute after Blackett was fouled by Paul Lorraine.
AFC Wimbledon boss Terry Brown told BBC London 94.9: "We were outplayed in the first half by a side that looked fitter, stronger and a yard sharper than us.
"To come out and really give it a go in the second half showed a lot of character.
"I said to the players before the game that this wouldn't show me if we were the best footballing side in the league but it would show me whether we the character to withstand full houses against good opposition, and they certainly did that."
Luton manager Mick Harford told BBC Three Counties Radio: "We're very disappointed with the way we played, especially in the first half.
"We should have been out of sight. We went 1-0 up, and could have been two or three up, but we didn't.
"We were guilty of not finishing them off and were undone by what was a tricky decision for the referee."
