Billy Batson, a 14-year-old boy living in Philadelphia and causing non-stop trouble for both social services and the local authorities in his search for his lost mother, is chosen by the Wizard Shazam to be his champion. Every time that Billy yells the word "SHAZAM!" he is transformed into an adult superhero. With his friend from the foster home, Freddy, Billy runs riot with his new powers, pushing them to their limits. However, the fun stops when Billy finds out that great powers come with even greater enemies. Billy's newfound nemesis is Dr. Thaddeus Sivana, a man who still harbours ill will towards the Wizard Shazam, who rejected Thaddeus as his champion years earlier, which resulted in Thaddeus choosing to harness the power of the Seven Deadly Sins (Greed, Pride, Lust, Gluttony, Envy Sloth and Wrath) instead.

Billy soon realises that being a superhero comes with responsibilities as he must learn the true significance of his powers in the fight against Sivana.
