What Remains

For the first 15 minutes of “What Remains,” we follow around a Scandinavian man named Mads Lake (Gustav Skarsgård), formerly Sigge Storm. Bearded, grizzled, timid, always wearing a Rukka outdoor coat — Lake is looking to start a new life after spending years in a psychiatric hospital. He tries (and fails) to get an apartment, gets mugged at knifepoint, and reconnects with his older brother. Right when you start to feel some sympathy for this poor sumabitch, therapist Anna Rudebeck (Andrea Riseborough) shows up and asks him this whopper: “What’s this about the nine boys you’ve molested?”
