The film concerns Matt's childhood from that of the death of his mother as well as Smith's terminal cancer diagnosis which leads to them growing closer to each other through professional wrestling after being near estranged for many years.

He began interacting with them after doing a project about Teddy Hart (Smith's nephew) that was put on hiatus for legal reasons which were later settled.

[4] Spenrath has explained that he spent a lot of time coming up with different "heart" related puns for the project but settled on "still beating" for fitting the theme that Matt Hart is continuing on with his life after the misfortune that befell on him.

[22] The film shows a flashback with a young actor portraying a 13 year old Matt finding his mother dead on her bed.

He speaks about how it was his 13th birthday and he and his mother had planned to spend the day together having fun but that when he arrived to the house she had passed out and been found by another person already dead.

Diana explains that this led to Matt being placed in foster care as the authorities did not deem his father a stable enough security to the boy at that time.

[27] Both Teddy and another family member Bronwyne Billington express how they wish they could have had their fathers (B. J. Annis and Dynamite Kid respectively) be there for their first matches, like Matt has.

[37] Isabel Rodriguez of SocialSuplex enjoyed the film feeling that its focus on the younger Hart over anything else was a good choice as it was the most engaging subject.
