Portsmouth 2-2 Argyle
After a frantic opening 20 minutes, Argyle showed great character to come away from Fratton Park with the scores level.
Pompey took the lead in only the third minute when Marc McNulty fired home after a mistake by Pilgrims captain Curtis Nelson.
But Argyle bounced back with two goals from Jamille Matt, the second a spectacular overhead kick that sent the travelling fans into ecstasy.
A penalty kick, taken by Gary Roberts, brought the sides level again five minutes into the second half, but Argyle hung on.
