After Mark and Valerie witness two giant archeologists get attacked by a man with a laser gun, they hide in hole, where they find a teleporter that sends them to an underground city called Limbo, which is populated by giants unknown to those living on the surface. Their leader, Taru, explains that if the archeologists discover Limbo, they will start a war, which the more advanced underground giants will surely win. Taru wishes to avoid war, but his rival, General Aza, is trying to start one and had sent the gunman to kill the scientists. With the others' help, Mark comes up with a plan to contaminate the soil at the dig site with an explosive chemical that would prevent the surface giants from blasting and discovering the hidden city.

For the Earthlings, at their scale, the war toys are just as lethal as the real things and must be stopped.

Steve and Dan encounter two time-travelling people their size, Throg and Berna, who escape an SID agent by using an amazing device called the "Space-Time Manipulator" (STM). Throg demonstrates the abilities of the STM, which can send anyone, to anywhere, to any time. Steve believes he could use the device to return to Earth and change everyone's current predicament by avoiding taking off for the fateful flight of the Spindrift. Steve manages to get a hold of the device, and Dan and he teleport back to Los Angeles spaceport on Earth just before the flight. Throg and Berna soon arrive and angrily explain that it is forbidden to change history, but Steve and Dan do not want to go back to the giant world so easily. Oddly, though the Spindrift left on their trip on June 12, 1983 in the pilot, their departure date here is September 25, 1983. Note: Series regular Stefan Arngrim (Barry) only appears in this episode via stock footage from the pilot. The storyline for this episode is lifted from the Lost In Space episode "The Time Merchant".
