Samuel Dantan, a human, long hunting the "men" of Martian "Redhelm Tribe" as
price of his revenge for killing of his (Martian?) girlfriend long back in a
raid by Redhelms, is finally cornered - alone, unarmed, pursued by a group of
Redhelms.
This is the situation in which he discovers the ancient buried lab of a
Martian scientist named Sanfel, now dead for centuries. Lab has a device that
opens a portal into a world called "Zha" in another universe - a universe with
different laws of Physics, where even time behaves very differently.
Sanfel built this gateway to help Quiana, a "woman" there cornered by an
"Enemy". Since Sanfel is long dead, Dantan will end up helping Quiana, & will
in turn get help ridding of his own Redhelms pursuers.
