A dramatic opening 10 minutes saw Guiseley have a man sent off when Harry Flowers pulled back Elliott Romain in the area, a penalty was also awarded, but Romain couldn’t beat Joe Green who made a smart save.
The Lions then went up the other end, with Curtis Morrison taking on the full-back and finding Dayle Southwell who added a decisive touch to make it 1-0.
Rhys Healy levelled for the hosts, but soon after Lions midfielder Will Hatfield took full advantage of miscommunication between the two Torquay centre-backs and placed the ball into the back of the net.
The second-half had an even start but the Lions were able to make it 3-1 when John Rooney crossed for Rowan Liburd who was well placed to loop a header in.
Torquay got one back when Healey headed in his second.
They pushed players forward and Guiseley were able to break on the counter and Liburd got his second of the game.
With time running out in the game, Healey had time to get his hat-trick with a header.
But Guiseley left with victory – only their seventh of a fraught season – and go into the last day of the season knowing they can move off the bottom of the table with a win or a draw and rivals Chester lose by five or more goals.
