Chester bounced back from defeat at Woking with an incredulous late show to win at Macclesfield.
Danny Whitehead gave the Silkmen the lead, before Tom Peers and Craig Hobson scored late goals to clinch an incredible win.
The Yellows started brightly, with full-back Johnny Hunt showing the attacking intent from the visitors - flashing a ball across the face of goal which Hobson just failed to connect with in the first minute.
Tom Shaw and Hobson would both hit weak shots when in space outside the box inside the opening ten minutes - as Steve Burr's side looked to have control of the game.
However, Macc did respond, with Kristian Dennis blasting a shot low and just wide of Worsnop's near post - Danny Rowe then fired over the bar, before Whitehead hit a low show which the visiting keeper easily gathered.
The Silkmen were growing in confidence, as home skipper Danny Whitaker forced Worsnop into action; palming his low drive round the post.
Following the home side's flurry of chances, the game seemed to take a lull in quality action - with John Rooney shooting over the bar less than ten minutes prior to the break.
Rooney really should have given the Blues the lead on the stroke of half time - but overcooked his touch with the goal at his mercy following good work by Craig Mahon.
Nevertheless, the home side took the lead on 53 minutes with the first real chance of the half.
A bouncing ball forward was poorly dealt with by the Chester defence, which resulted in Whitaker hooking the ball back for Whitehead to place the ball into the far corner of the net.
Rooney was looking like Steve Burr's most promising attacking outlet - being incredibly unlucky to have a 20 yard free kick headed off the line.
The visiting pressure was relentless, a Ryan Higgins long throw fell to substitute George Thomson; but his bouncing effort was incredibly hooked off the line by a Macc defender.
Chester's attacking prowess eventually would pay dividends, as Rooney's brilliant whipped free kick was scrambled home by Peers in the last minute of regulation time.
Then, incredibly, the Blues snatched all the points in the dying seconds in style - Hobson chested a long ball down, swiveled, and fired the ball into the corner of the net to send the away support into raptures.
