Would-be investigative journalists Peter (Christopher Denham) and Lorna (Nicole Vicius) go undercover and join the tiny, but growing cult of a reclusive young woman named Maggie (Brit Marling) who claims to have come here from the year 2054. Surely she's a fraud, but what if ... ?
The script, co-written by Marling and director Zal Batmanglij, examines the need to believe in something more and the need to question those beliefs. The low-budget mix of mystery and sci-fi effectively builds an intimate, ominous atmosphere without special effects or action scenes.
It's a head trip and a pretty good one, but what does Maggie stand to gain? If she's a con artist, probably money. If she's a mental case, probably something Jim Jones-ian. If she's a genuine time traveler, she might be here to change the past to improve the future.
The early indoctrination scenes with the undercover reporters grow tedious, but when Maggie makes a request involving a peculiar young girl, and a cop approaches one of the journalists, the story gets downright fascinating. In the end, you have to decide what the closing scenes mean. A minor movie, but captivating when it matters.
