The Spy Network of the United Kingdom (SNUK) is facing its greatest challenge yet. During a war with Japan, the UK government suffered a major security breach, which put the nation's safety in jeopardy. To address the situation, the government has assigned SNUK's top operatives to restore security. The team includes Sophia, the demolition expert, Oscar, the technology handler, and Theo ,Nathan, and George, the three agents. Together, they are confident that they can regain control of the leaked information and protect their country. However, the mastermind behind the breach is someone who seems familiar to the team.
