Los Angeles: New drama 'Allegiance' has been cancelled by NBC after only five episodes.
The cancellation, however, comes as no surprise since the show failed to attract a large number of audience since its premiere, reported Ace Showbiz.
Another newbie, 'The Slap' will take over 'Allegiance'.
'Allegiance' centers on Mark (Scott Cohen) and Katya (Hope Davis), covert Russian spies deactivated decades ago, who are re-enlisted into service as they plan a terrorist operation inside the US border.
This causes a conflict in their family as their son Alex O'Connor (Gavin Stenhouse) is a young idealistic CIA analyst specialising in Russian affairs who unknowingly is investigating his own family.
The show debuted to only 5 million total viewers and a 1.1 rating in the adult 18-49 demo on February 5, and the numbers kept falling since then. The latest episode pulled in 3.4 million viewers with a 0.8 rating.
