Young computer enthusiast Liam runs a website streaming video of his every action captured on a webcam. He lives a reclusive life, temporarily staying in a friend’s apartment in Paris until waitress Alison and her British husband, James, move in.
While waiting for a supportive housing, a couple, James and Alison, settle for some time in an apartment already occupied by a young man, Liam. This young roommate almost never leaves the apartment and indulges in a strange game: equipped with a webcam, it is filmed at any moment and re-transmits live images on his personal website. James and Alison, entering into Liam's daily life, become in turn "actors" of his site. The couple, apparently very in love, displays a free sexuality and is curious about Liam. As the days go by, a troubled relationship develops between the three protagonists. Alison enjoys being filmed by Liam. James, from his office, consults the site of Liam and discovers an Alison who, in front of the camera of the young man, indulges in an intimate way, evoking directly the special relationship she has with men. Through the camera, James finally understands that Alison does not like him as he imagined; Gradually, Liam becomes witness to the collapse of the couple.
