The series revolves around a computer program for the federal government known as "The Machine" that is capable of collating all sources of information to predict terrorist acts and to identify people planning them.
A team, consisting of John Reese, Harold Finch and Sameen Shaw follow "irrelevant" crimes: lesser level of priority for the government.
According to Nielsen Media Research, the episode was seen by an estimated 12.54 million household viewers and gained a 2.0/6 ratings share among adults aged 18–49.
Reese (Jim Caviezel) boards a plane to Rome after his original flight to Istanbul is delayed thanks to the Machine, planning to get away from his former life.
Finch meets with Shaw (Sarah Shahi) and discusses his idea that Matthews may be a relevant number and some organizations, including NSA and ISA are investigating him.
On New York, Shaw interrogates Hersh (Boris McGiver) after poisoning him, she finds that Matthews was made the Sphinx to cover their profits on the Black Market Bazaar and finance the ISA.
In its original American broadcast, "4C" was seen by an estimated 12.54 million household viewers and gained a 2.0/6 ratings share among adults aged 18–49, according to Nielsen Media Research.
The character of Owen was a bit too much, but watching Reese use most every found element on a commercial flight to battle his way through an avalanche of assassins was good stuff.
It's also an example of this show's action-thriller formula at its purest, because Reese rediscovers his sense of mission not through talking things out or exploring his feelings but through action.
