Returning for a third bite of the SPECIES cherry, director Brad Turner replaces the curvacious Eve (Natasha Henstridge, who makes a brief appearance) with her daughter and fellow hottie Sara (Sunny Mabrey). The battle between mankind and the human-alien lifeforms has gathered pace since the last frenetic round of SPECIES action, with the humans gaining a slight upper hand. But the emergence of Sara soon gives the aliens a vital boost to their efforts, with the deviously seductive hybrid heading to earth in order to repopulate it by reproducing as much as possible! Her incredible sex drive allows her to carry out the taxing mission, but a huge human military presence is gathering, aiming to put Sara and her cohorts out of action for good.
