Here is a French indie sci-fi in which a woman called Elsa (Megan Northam) mourns her brother Franck, who is missing and presumed dead in space, which makes him rather less likely to be found again. Elsa works at a care facility for elderly people and lives with her mother and younger brother; they are all stuck in the kind of limbo that comes with unresolved family mysteries. One day, Elsa encounters Franck once more – as a voice. It seems that an alien presence may be able to return him to his home planet, if Elsa is prepared to help them out with a little favour: the aliens require four people to be procured for them in exchange for Franck’s return. The people won’t be killed, but their personalities will essentially be erased or dampened to become hosts for the extraterrestrials.
