Cole is hesitant to make the same mistake twice, but agrees to visit the Bennett family, scientific researchers who are looking for more ecologically friendly ways of controlling wildlife.We meet the Bennetts, father Roy, mother Gerry, and daughter Amanda. Roy was capturing bats for an experiment. They want to control the bats' flight pattern, hoping to use them to kill mosquitoes, without the nasty side effects of DDT and other insecticides. Elgin Clark comes to see him and asks him to visit Cole, to see if he could come up with an ecologically friendly way to solve the rabbit problem. On the way there, they see ranchers desperately shooting at rabbits trying to preserve their livelihoods.At Cole's ranch, Cole explains his problem.
