The Undeclared War is a British near-future thriller television mini-series, aired from 30 June 2022 on Channel 4.

Parvin has just started a one-year student-placement at GCHQ when a cyber-attack takes down some of the UK-internet and she joins the team examining the code of the malware.

Meanwhile, she feels alienated within GCHQ but makes friends with John Yeabsley who spends his lunch-time correcting the grammar of other people's blogs.

Trusov eventually reveals that this was all planned by Russia and he deliberately and openly leaks all the Russian software to GCHQ as a gift that the UK can use to appeal for help from the USA just as the tit-for-tat reprisals become overtly physical.

The version in the show was provided by the London-based singers Evelyn Bates and Violet Verigo whose rendition is influenced by Pelageya's performance.
