Would be an interesting story about the production sound and post production process for this drama. Fantastic style (photography, costumes).
I grab the credits from IMDb
Dennis Towns - Production Sound Mixer
Shawn Allen - Boom Operator
Alfredo Viteri - Boom Operator
Karl Wasserman - Sound Utility
Reading an article on Indiewire, says 87% was shooted with single camera. You can notice that from cutting, but the transitions from actors, it's just perfect.
