Emma Mackey played my favorite character on “Sex Education,” Vicky Krieps is mesmerizing in everything she’s in (good and bad), and Fiona Shaw has done some consistently great supporting work in recent years (“Killing Eve,” “Echo Valley,” “Fleabag,” etc.). So when I heard that they were all doing a movie together, I requested a screener without even knowing the plot.

All three of these actresses keep their streak of fascinating work in “Hot Milk,” even if the story winds up going all over the place.

Mackey and Shaw play Sofia and Rose, a daughter and mother vacationing in Greece to help Rose overcome her health issues and delve into whether they are truly physical impairments or mental issues.

It is clear that the trauma of being her mother’s caretaker has worn down Sofia, and she finds some escape from those burdens in the form of a burgeoning romance with the ethereal and mysterious Ingrid (Krieps).

Even though Sofia is presumable in her later 20s or perhaps even early 30s, “Hot Milk” is very much a coming-of-age film that shows her doing some soul searching to figure out what she wants out of life.

Tension builds throughout the film, with Sofia facing frustration after frustration, both with her mother and in slowly discovering that her relationship with Ingrid isn’t really what she’s looking for in a partner.

Unfortunately, for me at least, this tension all builds up and is never completely resolved. I’m OK with open-ended films, because honestly, life can be open-ended at times, but in “Hot Milk,” it just kind of felt like the story fell apart.

Come and stay for three of the best actresses working these days, but don’t expect much more.

Rating: 3.5/5
