You don’t need to have seen the first two of this trilogy to… Well, enjoy is the wrong word for a movie this mysterious and offhanded. It follows a teenage girl—niece and daughter of the women whose tales centred director Ulrich Seidl’s previous flicks—sent to a summertime fat camp more notable for numbing routine than genuine exercise or diet control. Her escape from this loony place is mainly through fixation on a once-handsome doctor who reciprocates in ways that are opaquely disturbing. The movie doesn’t traffic in sensations but in uneasy (and unreliable) memories in the making.
