"Tru Calling"

While I never quite got into "Tru Calling", I was intrigued by the premise (and possibly I stopped watching because it conflicted with another show). Tru Davies, played by Eliza Dushku of "Buffy the Vampire Slayer" fame, was a young woman who discovered that she had the ability to jump back in time 24 hours, and affect the lives of someone who was in trouble (and most likely ended up dead). While the premise certainly drew on other shows ("Quantum Leap", the aforementioned "Nightmare Cafe", "Sliders") it was unique it its own way, and fans certainly weren't happy when the series was given the axe.

I was able to find the following information on what would have happened should been given a third season:

There are two great Powers in the universe concerned with humanity's fate; one that laid out the original plan that history has been following since the beginning of time, and one that wants to change that plan (what ultimate goal either side is working toward remains unknown, possibly even to the show's creators). The first power is more strict and authoritarian in its view of humanity, whereas the second is "more accepting of individual freedom and choice."
Whenever someone dies who may be important to the overall scheme of things (and, presumably, in a way that would serve the second power's purposes), an agent of that power approaches the person and offers them a choice- they can either move on, or return and have a shot at resuming their old life. If they want a second chance, all they have to do is ask for it. If they do, Davies goes back and relives the day, with a view to saving that person's life.
Every time Davies saves someone who has asked for her help, she steers the destiny of our world a little farther away from what the first power intended, and a little closer to what the agents of the second power want.
Harper, Davies' nemesis, has a very big advantage over her, her father was his mentor(who was Harper's predecessor, just as Davies' mother was hers). Davies is working in the dark, learning as she goes along, but Harper has an older, more experienced counterpart who can share knowledge and wisdom from a long line of predecessors with his young protege. Davies, of course, was robbed of this potentially crucial advantage because of her mother's untimely death.
Harper became Davies' counterpart after being approached by agents of the first power during his near-death experience. They offered him a choice: he could either die, or return to Earth to do their bidding. Once he got back, his memories of the encounter were hazy, and he didn't initially understand what was happening when his days started rewinding (at around the time that Davies' did). He eventually wound up in an asylum, which is where Davies' father found him.
The central conflict of the show's mythology was never meant to be perceived as a simple, straightforward "good versus evil" scenario. Rather, the creators intended to portray the battle in such a way that either side could conceivably be right- and, at the very least, to show that the soldiers on both sides certainly believe that what they're doing is right. Harper and Davies' father truly believe that she is disrupting the balance of the universe by doing what she does; Davies, of course, believes otherwise. Who would have turned out to be right? These are the questions the producers of the show meant for us to ponder.
A future storyline on the show would have dealt with the possible repercussions if Harper ever decided that he no longer wanted to fulfill his end of the bargain (i.e., to continue doing the first power's bidding).
Another storyline (which was actually in progress when the show ended) would have dealt with the consequences of Davies' saving someone who hadn't asked for her help. Because that person was either never given the choice to come back, or was and chose not to take it, he would have essentially lost his soul after being saved by Davies, and would then have begun spiralling into increasingly menacing behavior as his humanity faded away and his personality began to disintegrate.
