Plas began his career in martial arts in karate, learning Kyokushin from Jon Bluming. He founded the Mejiro Gym in 1978 after learning kickboxing from Kenji Kurosaki, a Japanese martial artist who founded the original Mejiro Gym in Mejiro, Tokyo. In 1976, he founded the NKBB (The Dutch Kickboxing Association) with Thom Harinck. He also went on to run the Vos Gym and trained many world-class fighters including Peter Aerts, Rodney Glunder, Ivan Hippolyte, Rob Kaman, Andre Mannaart and Fred Royers.
Plas was also a member of the Dutch organized crime world. In 1986, he was involved in the kidnapping of Gijs van Dam II, the son of hash dealer Gijs van Dam, with a gang run by the drug lord Johan Verhoek, also known as "De Hakkelaar". He worked as a bodyguard for well-known gangster Klaas Bruinsma. In April 2008, Plas was arrested on suspicion of drug trafficking and his daughter and son-in-law, both police officers in Amsterdam, were charged with fraud and money laundering.
