Proof (TNT, ABC Family)

TNT goes searching for life after death in its latest medical drama:

For millennia, the world’s greatest scholars and philosophers have tried to answer one important question: Is death truly the end, or is there something else beyond? Now a brilliant surgeon is ready to take up the mantle in TNT’s intriguing new drama Proof, starring Jennifer Beals (The L Word, Flashdance), Matthew Modine (And the Band Played On, Full Metal Jacket), David Sutcliffe (Private Practice, Gilmore Girls) and Joe Morton (Scandal, Terminator 2: Judgment Day). Beals plays Dr. Carolyn Tyler, who has suffered the recent, devastating loss of her teenage son, the breakup of her marriage and a growing estrangement from her daughter. Carolyn is persuaded by Ivan Turing (Modine), a cancer-stricken tech inventor and billionaire to investigate cases of reincarnation, near-death experiences, hauntings and other phenomena, all of it in the search for evidence that death is not the end. It’s both a journey of exploration toward finding an answer to a question many people have asked and a deeply personal and emotional journey for Carolyn, who hopes to find answers in the wake of her son’s death.
