Argyle returned to Home Park for another powerful display on familiar turf and a richly deserved three points over a dangerous Doncaster Rovers side.
The Pilgrims broke the deadlock on 34 minutes, when Luke Jephcott converted a sublime assist from Danny Mayor and victory was virtually sealed by a second from captain Joe Edwards midway through the second period.
Fejiri Okenabirhie did pull one back for a slightly uncomfortable final 15 minutes but Argyle stayed calm and composed in securing the victory.
