Tim is a geeky software developer who has created a tracking software on a disc. He meets with a gang leader named Dyl to sell him the disc but accidentally gives him the wrong disc due to his housemate Will mixing up the discs. Dyl gives Tim one hour to retrieve the correct disc or he will kill him. Tim rushes home but finds that two robbers have broken in and stolen the disc. One robber shoots the other and flees with the disc. Tim returns home in a panic as his time runs out, not knowing who now has the disc and with his life threatened if he does not get it back.
