BATMAN: VENOM illustrates that although Batman is a great hero, he is simply a human being underneath his costume. When Batman fails to save the life of a young kidnapped girl because of his own physical limitations, he turns to a performance-enhancing drug to increase his strength and stamina. But when the highly addictive super-steroid strips the Dark Knight of his control and morality, he must find a way to free himself from underneath its influence. Struggling with his addiction, Batman must make choose between using the drug again or facing his own probable demise.
