The Gardener (AKA The Seeds of Evil)

Ellen (Houghton) and her husband John (James Congdon) enjoy the good life in their lovely Costa Rica home-all that's missing is a nice garden. Enter the mysterious and dangerously handsome Carl (Dallesandro), who creates a botanical paradise while casting a spell on Ellen and her woman friends. Things take a turn for the worse when Ellen discovers that her Gardener may be planting his own "seeds of evil".
