SUBSTITUTE Luke Young saved Argyle from a third consecutive defeat with a superb 84th minute equaliser at Home Park on Saturday.
Young fired home a 25-yard free-kick to earn the Pilgrims a fortunate point from a 1-1 draw.
Cheltenham deservedly took the lead with a goal from striker Byron Harrison in the 53rd minute and seemed set for victory.
That was until Young, on as a second half substitute for Dominic Blizzard, again showed his prowess at set pieces.
The Plymouth-born midfielder also scored direct from free-kicks earlier this season in the 3-1 Devon derby defeat at Exeter City and the 2-1 home win against Dagenham and Redbridge.
Argyle went into the match without Andres Gurrieri, who was suspended after his red card in the 1-0 defeat at Rochdale last Saturday.
Gurrieri was replaced by Rommy Boco, who had not started a game since the Pilgrims lost 2-0 away to Chesterfield on December 14.
That was the only change to the starting line-up, while recent signing Matt Parsons was ruled out by a dead leg.
Parsons had been an unused substitute against Rochdale after signing for Argyle the previous day.
Cheltenham gave a Football League debut to on-loan Wolves centre-back Michael Ihiekwe, at the expense of the experienced Steve Elliott.
There was a low-key start to the match and the first scoring chance did not come until the 14th minute.
Boco was fouled by Cheltenham defender Troy Brown and Conor Hourihane curled the free-kick into the box.
It was met by centre-back Neal Trotman, who headed over the bar from close range.
Cheltenham twice went close to taking the lead in the 19th minute, first when Kemar Roofe shot low against the base of a post.
The ball rebounded out to Argyle centre-back Curtis Nelson, who stabbed it towards his own goal.
Luke McCormick was on the ground after diving to try to save Roofe's shot, and he scrambled up and scooped the ball away.
It was an incredible save by the Argyle 'keeper, and prevented Cheltenham from taking the lead with their first chance.
Ihiekwe then made an excellent block from Lewis Alessandra's goalbound shot in the 21st minute.
There were no more chances until the closing stages of the first half, when Cheltenham had a good spell.
Striker Jamie Cureton got on the end of a cross from right-back Sido Jombati in the 43rd minute but his volley was blocked by right-back Maxime Blanchard.
Moments later, Cureton linked up with Harrison and sent a curling 25-yard shot wide of the far post.
It was a poor finish to the first half from Argyle, who had rarely troubled the Cheltenham defence and lacked any tempo to their play.
Cureton had another chance only 20 seconds after the interval with a shot which clipped the top of the net.
Cheltenham were firmly on top, with Cureton having another snapshot comfortably saved by McCormick.
The visitors deservedly took the lead in the 53rd minute with a shot from Harrison which deflected off Trotman and went past McCormick.
Before play restarted, Argyle made a double substitution with Tyler Harvey and Young replacing Boco and Blizzard respectively.
The Pilgrims continued to struggle for attacking inspiration after that switch.
However, Young almost equalised in the 63rd minute with a fierce, swerving 35-yard shot which Cheltenham 'keeper Scott Brown pushed onto the left post.
Other than that one opportunity, Cheltenham were in complete control of the game.
Argyle's third and final substitution came in the 79th minute when winger Nathan Thomas replaced left-back Ben Purrington.
The Pilgrims played the rest of the game with three defenders as they pushed forward for an equaliser.
And Argyle did draw level in the 84th minute with a superb 25-yard free-kick from Young, beating Brown with deadly accuracy.
The set piece chance came after midfielder Matt Richards dived in and fouled Hourihane.
Jason Banton had a long-range shot saved by Brown in the 89th minute before striker Reuben Reid fired narrowly wide deep into stoppage time.
Despite the late pressure from, Argyle, it remained 1-1 until the final whistle.
