Interloper is a companion piece to Placebo.
The off-camera narrative is told from the doctor's divided point of view; as a phantom lover and placebo surgeon. He wakes up from a nine-month coma, has a near death experience and floats above his deluded self through the basement bowels of a hospital. He briefly realises that he has become fiction as he sees his character carry out unqualified medical operations. A clue to his state of mind is offered when he realises he grew up in an experimental lab, a secret incubator of young prodigies that was housed in the basement of the hospital.
Interloper is filmed underwater with a camera going through the interiors of submerged sets dipped in paint.
The electronic soundtrack is by Jem Finer.
