A large black box crashes through the sky, landing on an unnamed man's head (an intense and brooding Tom Sturridge). He spends long months recovering, having lost all memory and sense of self. Bursts of intense déjà vu start to plague him and, after a multi-million pound settlement, he becomes increasingly extravagant in enacting fragments of memory. The director Omar Fast offers a narrative that is purposefully obscure, complex and almost certainly not what it seems.
