The reluctant time travellers are trapped in a a strange temple on Mars where Time stands still.
They are accompanied by 12 strange and ancient mythological Gods and a Mr Puddlewick, a bank teller from Threadneedle Street, who while attending a lecture by Mr Tesla on communicating with Mars suddenly found himself transported there.
None of them know why, nor the signifcance of what is behind the frescos which adorn the walls of the Time Palace of Mars.
But they do have a strange device which can change time. Though whether it changes time is inside or outside the palace, no one knows.
