Edward Wozny, a hot shot young banker, is sent to help one of his firm's most important and mysterious clients. When asked to uncrate and organise a personal library of rare books, Edward's initial indignation turns to intrigue as he realises that among the volumes there may be hidden a unique medieval codex, a priceless bound manuscript that has been kept sealed away for many years and for many reasons. Edward's intrigue becomes obsession that only deepens as friends draw him into a peculiar and addictive computer game and mystifying paralells begin to emerge between the game's virtual reality and the legend of the codex.
