Poppy (Annie K. McVey, who also directed) is making a documentary on homeless people in Los Angeles when she comes across an odd man camping out in Griffith Park. This is Alistair (Guy Birtwhisle, who also wrote the script) He's dressed in old style military clothes and speaks with an English accent. She (and the cameraman and audio guy) learns that he's been transported from the battlefields of WWI to present day via a "hole" he came through. At first they think he may be crazy but he's so sincere that Poppy begins to believe him and goes out of her way to provide him food and eventually shelter. Eventually we're introduced to Poppy's ex, Sophie-and she's a scientist who may be able to help them figure out where the wormhole is open, so Alistair can return to his wife.
Although it's a low-budget, through-the-eye-of-the-camera type of movie, it does keep your interest and is along the line of SAFETY NOT GUARANTEED. Recommended.
