The One with... the exploding bracelets.
The Erdmann gang, a group of notorious criminals, have developed a new and ingenious method of getting civilians to do their dirty work - they strap timed explosives onto their wrists and plant the key where they want the explosives taking. Their first victim barely survives - thanks only to International Rescue's new fireproof rescue elevator - but the records of the Erdmann gang do not.
Furious at this development, the security forces send British agent Southern to infiltrate the gang, armed only with a radio-transmitter pen. While this agent is able to infiltrate the gang's effort to break into a plutonium store, he's captured by one of the guard robots and left to die. It's up to International Rescue to reach the explosives before a nuclear holocaust engulfs Scotland!
- Drives Like Crazy: Thomas Prescot. Justified, you'd drive like that too if you had a bomb strapped to your wrist and only 30 minutes to reach the key to take it off.
- Elevator Failure: Caused by a honking great explosion.
- Explosive Leash: The favoured tactic of the bad guys in this episode.
- Faking the Dead: Thomas Prescott, the first victim of the Erdmann Gang's MO with the explosive bracelets, is saved in time by International Rescue, yet British intelligence decides to publish a fake newspaper article that Prescott has perished in the fire in hopes that the Erdmann gang will feel save enough to try the same trick again. It works.
- Hostile Hitchhiker: Prescott becomes a victim of the Erdmann gang when he picks up a hitchhiker, who turns out to be a member of the gang and straps the bomb to his wrist.
- Relocating the Explosion: Scott does this at the climax of the episode.
- Spy Fiction: Leaning a little towards Stale Beer. The visual style was heavily inspired by The Ipcress File, which the crew had seen that weekend, but there's also some Bond shout-outs (It wouldn't be until "The Man From MI-5 that they'd go "full Bond").
- Western Terrorists: the Erdmann gang
- Tin-Can Robot: The storehouse's (rather adorable) guardbots. Leads to a little Zeerust.
- You Have to Believe Me!: Prescott when he is arrested after his rescue. Fortunately for him, British Intelligence does believe him about the bomb bracelet, especially after remains of said bracelet are recovered from the debris.
