After entering one of the mysterious pylons, Will and Holly find that their actions have messed with the weather and created a terrible storm that is dealt with by three mysterious flying objects.

Rick must work with an outcast Sleestak named S'latch (voice by Ralph James) in order to climb out of the pit in which they have been left to die.

Cha-Ka is invited to dinner by the Marshalls, but when Holly dabs on some perfume she has (leading Rick to mutter, "Our little girl is growing up to be a lady") it causes the other Pakuni to capture Holly — and draws out the land's ruling T-Rex.

When Rick is almost electrocuted by crystals, Will must convince Enik to save his life, but finds that his time doorway has settled on Earth — leaving him with a bitter choice.

Cha-Ka and Holly come under the control of a malevolent being that is seeking more power for one of the pylons.

Grumpy's attraction to ground hugging ferns Holly has nicknamed "dinosaur nip" causes the Marshall children to dump it over a cliff, where they discover a mysterious diary that holds clues to a possible escape from the Land.

Rick is captured by the Sleestaks and blamed for a malfunctioning pylon which prevents the sun from setting.

Rick and Will follow the Pakuni to a special pylon that seems to be linked to Earth. Holly enters the pylon searching for her family and discovers that the pylon is a portal, rapidly shifting between times and worlds.

Will and Cha-Ka go fishing, while Holly prepares a special meal. When Holly runs afoul of a noxious plant, the Marshalls appeal to Ta for help.

Holly has an encounter with the stranded Zarn.

Exploring ruins left by an advanced humanoid civilization, the Marshalls and Cha-Ka find an artifact that has a special impact on one of their party.

When quakes rattle the land, the Marshalls encounter mirror images of themselves who need their help.

The Sleestaks tamper with a pylon in order to create eternal darkness, forcing Rick and Enik to consult the Library of Skulls in order to find a way to set things right.

A mammoth earthquake shatters the land, opens a temporal pathway in which Rick Marshall falls and thus returns home, and brings to the Land Will and Holly's uncle, Jack.

After Holly falls ill, Jack bargains with the barbarian Malak (Richard Kiel) for the medicine that was stolen from them.

After a new pylon turns Will invisible, he is persuaded by a captured Enik to use this ability to retrieve a sacred orb and exchange it with the Sleestaks for the Altrusian's freedom.

This wasn't written as a series finale, so Will and Holly Marshall are never seen escaping from the Land of the Lost, although an alternate version of them and their father did return to Earth in the final episode of Season 1.
