A woman's husband has been missing for seven years. Now she's pregnant with the child of the investigating detective and is ready to move on with her life--when he shows up at her doorstep. And he looks exactly like he did when he went missing. It turns out that he fell into a different dimension where a weird-insect like creature lives and feeds on humans. In this neighborhood, it's living in a walkway tunnel that goes underneath a road. It reminded me a bit of MIMIC crossed with the story of the Three Billygoats Gruff. This monster movie is much better than I thought it would be. Recommended.
