A product of EV Dielsdorf-Niederhasli, Plüss made his debut for EHC Kloten in the Swiss top-flight NLA in 1994.

In 2004, he left Kloten to join Frölunda HC in the Swedish Elite League and helped the team capture the title in his first year.

Plüss' contract expired once again in the spring of 2007, but he turned down offers from primarily Swiss teams to instead sign for three years with Frölunda.

After a disappointing 2008 season, Plüss canceled the remaining two years of his contract with Frölunda, stating his game had not developed as expected.
