After their environmentalist mother (Beth Grant) disappeared into the waters off her lakefront home, sisters June (Lindsay Burdge), Annie (Jennifer Lafleur) and Isa (Aleksa Palladino) convened there to settle her affairs. The somber reunion for the troubled sibs will take bizarre and disturbing turns after a playful attempt to invoke the spirits of the lake's drowned yields unsettling consequences. Writer-director Sarah Adina Smith's slow-burn shocker co-stars Ross Partridge. 84 min.
