A malevolent alien species has been abducting humans for decades...possibly centuries. Their endgame: to harvest enough human emotional energy to open a wormhole through which their spacecrafts can pass and conquer our world. To end this threat, the U.S. military initiates Project Ithaca, a top-secret plan to teleport a human-alien hybrid, SERA, aboard the "mother ship" to destroy it. SERA awakes inside the alien craft along with five others. Divided, they will die; only together, can they defeat the aliens and find a way home.
