Jared, a new father, fears parenthood. An old comics fan, he turns to them for comfort. But when he unwittingly lets loose his favorite character, Killstrike-a single-minded, vengeance-loving anti-hero-onto the world, Jared must find a way to send him back before he harms all the people he loves the most. But before that happens, Killstrike leads Jared on a quest of self-discovery to make him realize the kid who loved this character is not the man he has become.

Killstrike and Jared travel to New York City to visit the comic book company his father was employed with before his disappearance. While waiting for the meeting, Killstrike gives Jared a few lessons on being a "tough guy."

Having kidnapped the artist who worked with Jared's father back in the '80s, Jared and Killstrike have to infiltrate a comic convention to keep up appearances, and Killstrike receives tons of accolades for what appears to be the best cosplay of all time.

Jared and Killstrike face off in an epic showdown, and Jared must make a life-changing choice.
