Overview

Two schoolchildren are recruited by MI6 to infiltrate a quiet North Essex school suspected of concealing a secret plutonium purification operation - and have just 30 minutes to uncover the truth before it's too late. When MI6 uncovers evidence of an illegal plutonium purification operation hidden within a quiet North Essex school, two unsuspecting students are recruited for a covert mission. Posing as ordinary pupils, they must infiltrate the site, gather proof, and dismantle the scheme before it reaches a critical stage. But the deeper they go, the more dangerous the truth becomes - as they uncover a pair of ruthless brothers, suspected to be the architects of the operation, working from the shadows. With the threat of exposure-and detonation-hanging over them, the clock is ticking fast. They have 30 minutes to get out alive.
