West and Gordon ensure that the Crown Jewels of Herzburg arrive safely at the museum where they are to be exhibited, only for them to disappear almost immediately from a locked room. The agents become suspicious of Axel Morgan, a wealthy rancher, when Gordon notices that a painting which Morgan donated to the exhibit is a forgery. It soon emerges that Morgan is in collusion with Dr. Loveless. This time the mad genius has invented a way of entering and leaving paintings via the use of sound waves. He's also sent for Lightnin’ McCoy, master gunslinger, whom he plans to employ in a showdown with West.
Tropes present in this episode:
- Artistic License – Physics: This is applied liberally throughout the series, but it's usually subtle enough that suspension of disbelief can cover the discrepancies. Usually. When this episode shows people hopping in and out of paintings through the use of sound, however... just... no.
- Bandito: Lightin' McCoy turns out to be one of these.
- Duel to the Death: This is what Loveless hopes to set up between West and McCoy. The agents manage to foil his plans... mostly - the two men still end up squaring off. Not surprisingly, Jim wins.
- Fastest Gun in the West: Lightnin' McCoy, reputedly. When put to the test, it turns out he is - er, was - second best, at most.
- Girl of the Week: Averted big time - this is the only episode of the series with no female characters at all.
- The Starscream: Axel Morgan to Dr. Loveless. Neither is very willing to play second banana and after a lot of infighting, Morgan finally attempts a double-cross.
- Stating the Simple Solution: Axel Morgan advises Dr. Loveless to just kill West immediately. Loveless does not take his advice well.
- The Stoic: Lightnin' McCoy. "He was very fast, Señor."
- Trojan Horse: Dr. Loveless plots to hide assassins in a collection of forged paintings and then donate the paintings to various world leaders. The assassins will then emerge and kill the leaders, thus allowing Loveless to rise to power.
