Five students unwittingly set off a spirit clock in a rundown London mansion. As the boundaries between fantasy and reality become blurred, the friends reveal their darkest secrets and begin to lapse into a haze of paranoia and violence.

In London, four students have a call from the student accommodation office of the local university offering lodging in an old house. The psychic Jenny, the graphic design student Nick, and the couple of lovers/drug dealers Tom and Adele are welcomed by the weird Tina. Nick fixes a spirit clock, and soon Jenny sees the crimes that happened in the house in the past, when two lovers died. Along the two next days, Jenny, Nick, Tom and Adele disclose that each one of them have killed a person in the past and also that they are trapped in the house, since a ghost is claiming a killer for a killer to release the soul of Edmund Joseph.—Claudio Carvalho, Rio de Janeiro, Brazil
