1975, the year after the Carnation Revolution. Eduarda, João and Mick come from Northern Europe to work in the co-ops in the occupied farms of central Portugal. Like many others, they come to help with the land and the livestock, give medical appointments, family planning classes, show sexual education films and participate in the traditional dances. They bring a great deal of questions, but the “comrades from the South”, in turn, have more questions than answers.

The Gardner family moves to a remote farmstead in rural New England to escape the hustle of the 21st century. They are busy adapting to their new life when a meteorite crashes into their front yard, melts into the earth, and infects both the land and the properties of space-time with a strange, otherworldly colour. To their horror, the family discovers this alien force is gradually mutating every life form that it touches—including them.

If ghosts can think and remember who they are, then the physical brain is not the only place where we store our inner selves. Helen is asked to train two young women into the art of communicating with the dead. But Helen's days as a medium are long gone. In fact, she gave up that life 15 years ago when she lost her daughter. Today Helen is a different woman dedicated to her career in brain research. Things start to change when a visit from the other side offers her the design of a device that can do amazing things. But to everything there is a risk.
