 A Little League outfielder chasing a fly ball gets a whiff of what s beyond the fence -- and collapses. He s been poisoned by a chemical spill from a pipeline just beyond the fence which is carrying illegal toxic chemicals. The boy s father (Max Gail) chains himself to a company billboard to get attention to the company s policies. This was the last "regular" episode for Gregory Harrison as Gonzo Gates (he did seven of the first 10 shows in the last season; the one after this is his going-away episode).
