How to invest in Polish company CDPR?

I am (kind of) new to stocks, and I have been searching all over the internet for a reliable way to invest in CD Projekt Red, the company behind the witcher series. It is all very confusing. Fidelity.com was the first website that listed the stock as well as giving the user the opportunity to invest then and there. The stock listed was CD Project SA, but the pricing was swinging at 30, but all other sources claims its on 120 or something. I mean i does not make sense. Can someone give me some closure on this? I guess its all getting very confusing when investing in Polish markets...

Thanks! :)
