Resident computer genius Harold Finch has the useful ability to unblock any plot obstacle. He simply mutters some stuff about cloning or firewalls and suddenly he can penetrate any system, view any CCTV, access anyone’s emails.

Tonight he tunes into a household’s wifi from outside in the road using only a crisp tube – clever. But he’s not perfect, it turns out. A mysterious female computer genius with black fingernails manages to compromise his network and suddenly the boot’s on the other hard-drive.

About this programme

The Machine comes up with the social security number of project manager Scott Powell, who had been laid off several months ago from a position in the construction industry, although his wife is unaware of the fact. Reese and Finch discover that he recently applied for a firearms licence and had been e-mailling threats to a congressman he blames for the loss of his job, but matters are complicated when Finch realises the man's computer has been hacked. Crime drama, starring Jim Caviezel.
