Zach tackles the ultimate existential question as he explores what happens when we die and whether or not we can have life after death. He meets with a Texas man who actually died and came back to life after a horrific kayaking accident. Zach continues his search by attempting to speak with spirits from beyond the grave with the help of a father and paranormal investigator who claims to have audio and video communication with his deceased daughter. Zach also looks at the strange world of cryogenics at the infamous Alcor laboratories in Arizona, and he uncovers a breakthrough anti-aging pill that is being developed inside the labs at Harvard University.
