Ben House scored twice as Lincoln netted two late goals to beat Luton 3-1 at the LNER Arena.
House had given the Imps a half-time lead with a 12th-minute strike, but Jordan Clark equalised for Town after 77 minutes.
Substitute Justin Obikwu smashed City back in front in the 83rd minute, before House sealed the points with a sublime 90th-minute goal.
City nearly took an early lead when Adam Reach's inswinging free-kick from the right crashed against the crossbar.
The Imps did not have too much longer to wait for the opener, though, as Freddie Draper dissected the home defence with a ball through to House, who confidently stroked past Josh Keeley.
Draper brought a flying save out of the visiting keeper with a vicious effort, then tested him with an overhead kick.
Former Hatter Sonny Bradley should have made it 2-0 after 74 minutes but slammed a close-range shot over the bar.
And that miss came back to bite City, with Clark levelling from a well-worked Luton free-kick.
City regained the lead when sub Tom Hamer put through Obikwu and the loanee hit a powerful shot past Keeley.
And House secured victory when he cut inside from the left and curled a shot into the far corner.
