Synopsis:
When Doc tries to install a responsometer in the Sizzler, an explosion occurs. The Sizzler is destroyed, and Doc is injured. Gold operates on Doc, who survives, but remains in a coma. Tina pledges to stand by Doc's side until he recovers. Meanwhile, Gold leads the rest of the Metal Men on patrol.

The Metal Men soon encounter Chemo. The chemical menace begins picking off the Metal Men one at a time, until only Gold remains intact. Tina refuses to leave Doc's bedside to help. When Chemo approaches the lab, Tina finally joins in the fight. Gold and Tina then destroy Chemo. Doc eventually recovers, and the other Metal Men are repaired.
