In the U.S. Virgin Islands, green iguanas are dramatically increasing in number and spreading. The situation has left most humans and iguanas scratching their heads about how to get by in the fast-changing island environment. The film engages in a lively debate about when and where animals are welcome, and if it is possible to create environments where it is easier for humans and all species to co-exist. Of mounting concern is the challenges to balance local agricultural production and space for the iguanas.
