When agents start dropping dead of natural causes at an alarming rate, Steed, Gambit and Purdey find that the only common factor is that they had all gone on leave after taking target practice on a special shooting range run by operative Bradshaw.

When Gambit plays an unintentionally fatal trick on Bradshaw, by shooting him with the guns from the course, he discovers that ink-squibs on the range contain deadly curare. The shooting range has been taken over by Draker and his midget assistant Kloekoe, two enemy agents bent on killing the department’s agents.
