Charlie (Michael Shanks) tries to comfort spirit Alex (Erica Durance) in the OR as they watch Dawn (Michelle Nolden), Maggie (Julia Taylor Ross), and Reycraft (K. C Collins) struggle to repair her heart. Before spirit Alex can fully comprehend that she's dying on the operating table and that Charlie really can see ghosts - she pops - waking up in a "dream” that takes her back to her childhood home in St. Catharines, Ont. A chance encounter with a lost loved one puts Alex face-to-face with a repressed memory that holds the key to her past, present and future. Meanwhile, Dawn (Michelle Nolden) manages to stitch the hole in Alex's heart, only to be convinced by a passionate Charlie that something may still be wrong with Alex - leading the team to discover a deadly mistake that Dawn has only minutes to rectify. Joel (Daniel Gillies) is pulled to the ER to treat Alex's assailant - and when his patient pleads to let him die - Joel's morals as a man are tested against his ethics as a doctor.
