[4][5][6][7] Heal begins with an opening monologue from Noonan-Gores in which the director states her concerns about the growing cases of disease due to the toxicity of the environment and food people consume.

Bruce Lipton, Joan Borysenko, Gregg Braden, and Darren Weissman discuss stem cells, genetics and the role of the environment on one's health.

The film then refocuses on Eva Lee, who is in a therapy session with Patti Penn, a Reiki master and Emotional Freedom Technique practitioner.

Noonan-Gores, Joan Borysenko, Marianne Williamson, Deepak Chopra, and Kelly Turner discuss the role of meditation in relieving stress and activating the parasympathetic nervous system.

[4] John Defore wrote in The Hollywood Reporter that "the general theme is a belief that most modern pharmaceuticals and the doctors who rely on them are ineffective at best, harmful at worst", and that the film does not have a good command of science.

[4] He describes the directing as "committing the usual newbie-docmaker sin of framing this fact-gathering exercise as her personal journey", adding that "Noonan doubles down in sometimes silly ways".

"[4] Writing for Slate Magazine, Marc Siegel stated that the movie "spends hardly any time exploring the scientific underpinnings of the miraculous cures it highlights, or why they frequently fail for others".

[6] The Los Angeles Times reported that the movie "appears closer to a feature-length infomercial than a legitimate documentary" and that the director had made "odd choices that distract from her message".

[7] Leigh Monson wrote that the film pushes an agenda by leading viewers to falsely hope for better outcomes based on wishful thinking.
