Tru Davies is the show's main character, portrayed by Eliza Dushku.At the age of only 12 years old, Tru witnessed the murder of her mother, Elise Davies.
After her mother's demise, Tru, her younger brother Harrison and older sister Meredith were abandoned by their father and little has been revealed about who raised them from that point on.Tru possesses the power to relive the current day when a corpse asks for her help to turn back the clock in order to save his/her Life, or help someone whom the corpse affected in some way.Mostly triumphant, Tru has on occasion been unsuccessful in saving lives, sometimes because of the interference of Jack Harper and sometimes because the corpse was not meant to live. An instance of this was when a group of five corpses all asked for her help at the same time.Other times her day rewound more than once on an already rewound day, as in "The Longest Day" and "Grace".In "The Last Good Day", when a dead woman asked Jack Harper for help, Tru finally discovered what Jack saw when a corpse would ask her for help.Davis is Tru's supervisor, friend, and confidante at the Morgue. Years ago, Tru's mother tried to warn him of the car accident that was about to happen.
He didn't heed the warning, but Tru's mother flattened his car's tires, thus saving his life, but unable to save his spouse.
Spending years living in regret and guilt, now acts as a mentor to Tru.
She described this as a Dark Feeling which she would never want to experience again.
Although both can relive days, it has never been said who is evil, Tru or Jack.
Jack has always been portrayed as evil, which Jack denies, although at certain times Jack has broken the rules of preserving fate, such as to make Luc die to teach Tru a lesson.
While Tru claims that she is saving people who were taken before their time, Jack claims that he is merely preserving fate, and that if Tru saves someone who is meant to die, she creates a ripple effect in fate.
