This is Wagner's Tristan und Isolde from the Bayerische Staatsoper. It's a regie production, naturally. Almost everything from there is. I'm not sure it provides a context. They all wear modern clothing, and we don't seem to be on a ship.
Tristan has traveled to Ireland to bring back the future bride of King Mark of Cornwall. He is there in his official capacity as representative of Cornwall. Actually Tristan and Princess Isolde have an already existing relationship. In a war between the two kingdoms, Tristan has killed Isolde's fiance and been seriously wounded in the process. Isolde with the help of Brangäne nursed him back to health.
On the journey she tries to order him around. He remains distant and sends his assistant, Kurwenal. This bit is not precisely clear. Brangäne prepares a potion that Tristan and Isolde are to share. Tristan drinks half, and then Isolde drinks the rest. They seem to think it will kill them, but instead they fall hopelessly in love. I thought the sudden falling in love was well handled. We appear to be doing social distancing in this production. No one touches in this part.
