It seemed so harmless at first. Concrete was just going to observe a group of Earth First!ers -- to see firsthand what they were all about and to write about their efforts to save an old-growth forest. But that was before the group talked Concrete into illegally entering Canada, and before they decided to "monkey-wrench" some logging equipment, and before the owners of that equipment unexpectedly showed up. Now it's up to Concrete to save them all -- even if it means risking his own life.
