In the titular life-sustaining structure, White House science advisor Ray (Sterling K. Brown) and lifelong pal and old boss Billy (Mark Duplass) were becoming accustomed to possibly being the last people remaining on Earth. As the reality of their situation sinks in and relationships become strained, Billy finds himself adapting to the new reality in an unexpected fashion, in this darkly observational apocalyptic two-hander farce, co-scripted by Duplass and director Mel Eslyn. 106 min. Widescreen; Soundtrack: English.
