Paul Ziller directs this disaster movie following the havoc wreaked by a giant root system that grows at an exponential rate and tears through everything in its path. A pair of environmentalists, Kate (Luisa D'Oliveira) and Joe (Jesse Moss), are among the first to encounter the bizarre phenomenon of the root, but so great is the damage it causes that it is soon a matter of widespread concern. Government agent Jack Taylor (Adrian Pasdar) is one of those tasked with finding a way to contain the problem and seeks out plant expert Jocelyn Snow (Stefanie von Pfetten) for her advice. There are a range of theories on what may lie behind the dangerous plant system, but Jocelyn is convinced that the seed engineering of Frame Marcos (James Morrison) is at the heart of it.
