Becca shows up on Butcher's doorstep and begs for his help. The Boys agree to back Butcher, and together with Starlight, they finally face off against Homelander and Stormfront. But things go very bad, very fast.
Superpowered individuals are recognized as heroes by the general public but owned by powerful corporation Vought International, which markets and monetizes them. Outside of their heroic personas, most are arrogant and corrupt.
The Seven (Vought International's premier superhero team) are led by the egotistical and unstable Homelander, while the Boys (vigilantes looking to keep the corrupted heroes under control) are led by Billy Butcher, who despises all superpowered people. As a conflict ensues between the two groups, the series also follows the new members of each team: Hughie Campbell of the Boys, who joins the vigilantes after his girlfriend is killed by one of the Seven; and Annie January / Starlight of the Seven, a young and hopeful heroine forced to face the truth about the heroes she admires.
