Betty (Barbara Auer) takes care of Laura (Paula Beer), a piano student, after she survives a car crash that kills her boyfriend in Miroirs No. 3. She lets her stay at her home and invites her estranged husband, Richard (Matthias Brandt) and son, Max (Enno Trebs), over. Writer/director Christian Petzold has made an understated and quietly moving  meditation on grief. He begins the film with the car crash; there's little to no first act or exposition that sets up the relationship between Laura and her boyfriend. Miraculously, Laura survives the crash with just a minor cut. Betty seems sad, depressed and lonely. Her faucet constantly drips, her dishwasher and one of her bicycles are both broken. When she tells Laura that she's inviting her husband and son over, she refers to them as "the men." They happen to work as mechanics, so they insist on fixing her faucet, dishwasher and bicycle. Very little happens in terms of plot, but there's a twist near the end that helps to add more emotional depth and to explain where Betty's sadness comes from. Interestingly, Laura and Max don't develop a romance, although they do flirt a little. This isn't a Hollywood film, after all. There's also some surprisingly lively use of music during a few scenes. Paula Beer and Barbara Auer give warm, nuanced and radiant performances that ground the film in humanism. They're both wonderfully natural actresses who get many chances to shine here. The unconventional ending feels abrupt, though, although it does leave some room for interpretation. At a running time of only 1 hour and 26 minutes,  Miroirs No. 3 opens in select theaters via 1-2 Special.
