TBI survivor Derek Dabkoski enrolls in an experimental stem cell surgery study to have stem cells injected directly into the injured area of his brain. He hopes to regain the functionality he lost when he was brutally attacked and left for dead on the streets of San Francisco a decade ago. He enrolls in this surgery at a difficult time for his family, as he and his wife Nadia, his primary caretaker restricted by their long and fruitless fight for her green card, are about to have their first child.
