Taking even themselves by surprise, a biologist with the Army Corps of Engineers, a satirist and a bunch of boaters stand up to the authorities, and change the course of history for an embattled environmental landmark.
In the Spring of 2008 the Army Corps of Engineers declared the LA River "non-navigable", thus excluding it from protection under the Clean Water Act. Enter Heather, a biologist working for the Army Corps, who cannot simply stand by and see this natural resource fed to developers, and who leaks the internal memo to her congressman, Henry Waxman. A media storm descends on the issue, and George Wolfe, a satirist and avid kayaker is caught in the beam of public attention. Why? Because he'd been planning a trip down the entire river, just for fun. Emboldened by Heather, his expedition suddenly gains a higher purpose, and a dozen intrepid boaters volunteer to participate and confront the authorities, and demonstrate the navigability of this river.
