What if your only sister was brutally murdered and you could go back in time to save her? Would you? For scientist Philip Davis (Dean Paul) that´s a no-brainer decision since he´s developed a way of traveling back in time. So, of course, he does just that! But in saving his sister (Laura Giglio), he dooms his own wife (Suzi Leigh) when she becomes the victim of the sadistic strangler! And despite going back in time, again and again, Philip only makes things worse.
