Space: 1999

Commander John Koenig arrives at Moonbase Alpha, where he is faced with a mysterious disease afflicting personnel and an escalating crisis at its nuclear waste dumps that will rip the moon from its orbit.

A terrifying force from outer space brings freezing death to the personnel of Moonbase Alpha, and one man has been chosen as the instrument of destruction.

An ancient alien queen (Margaret Leighton) persuades Koenig to allow their moon to collide with her planet.

Moonbase Alpha finds itself at war with an unnamed planet. Unfortunately, the outcome is disastrous with death and destruction everywhere. Are the Alphans doomed or is there a future for the survivors on the aggressor planet?

Commander Koenig and his colleagues speed through space and time into a chilling world of ice. However, once there, they encounter people who appear to be former inhabitants of earth stranded there.

Revenge-seeking aliens complicate matters as the crew tries to incapacitate a deadly ship containing valuable information.
