A group of three housemates in Glasgow is looking for someone to fill the fourth bedroom in their large apartment. The trio—"Juliet," portrayed by Kerry Fox, a doctor; "Alex," played by Ewan McGregor, who works as a journalist for a tabloid; and "David," with Christopher Eccleston in the role of an accountant—seemingly get along despite their different backgrounds. It's Juliet who initially encounters "Hugo" (Keith Allen), and he manages to persuade them – primarily through offering a substantial sum of money – that he’s exactly what they need. After he retreats into his room, and following a few days without any contact, the others are forced to break down the door and discover him deceased in bed, alongside a suitcase filled with money. The question then becomes: should they alert the authorities or handle the situation themselves? They opt for the latter course of action, which plunges them into a sequence of increasingly dangerous situations that permanently alter both their lives and their bond. While the storyline is admittedly unrealistic, the characters interact effectively as their initial sense of harmony deteriorates amidst suspicion, avarice, and violence. I found Miller’s performance to be particularly noteworthy, and Colin McCredie provides an enjoyable turn as the prospective roommate "Cameron," while Ken Stott brings a distinctive style to his role as policeman “McCall.” Certain aspects of the plot don't quite add up, but these inconsistencies are ultimately unimportant because this humorous exploration of human nature moves along at a brisk pace for ninety minutes.
