First there was Ditchmen, where teacher, Jay Griner, saves his hometown from an invasion of Ditchmen.
This invasion turned out to be the out-of-control research of his supposedly deceased wife, Amy.
Then there was Ditchmen 2, where a government-organized task force attempts to steal Amy Griner's Ditchmen research. Amy foils their plan with the help of her husband, Jay Griner.
Next there was Ditchmen 3--one member of the government organized task force attempts to duplicate Amy Griner's Ditchmen research. Once again, the diabolical plan is foiled, but a mutated form of a Ditchmen is created.
Now in Ditchmen 4, Turfie, the mutated Ditchman, must help Jay and Amy foil the twisted plan of another member of the government-organized task force to eliminate a newly discovered cryptid in order to preserve their climate crisis agenda.
