Where to watch the Estonian TV series “Merivälja” with subs

Long story short, after falling in a deep rabbit hole preparing for an upcoming trip to Tallinn, I would love to watch the TV series "Sea field"regarding an apparent UFO crash discovery in a garden (!) in the suburbs of Tallinn of which it is known even today the exact house number.
The series is available for free and it seems without geo fencing (I’m based in Latvia, hello neighbours!) on TV3’s website
https://play.tv3.ee/series/merivalja,serial-1024219/osa-1,episode-1035134

But it is in Estonian, and without subtitles in any language.
Do you know if there’s another source for this? Preferably with subtitles? I cannot find anything, but – maybe it’s available in DVD with SUB?
I will be in Tallinn for a long weekend in two weeks, so even a physical copy would be a nice souvenir, considering that I plan to have a – very respectful – drive through Hõbekuuse tee.

Thank you!
