Years after hanging up his cape, a retired Clark Kent lives a quiet life on the Kent farm in Smallville with Lois Lane and their two children, Jon and Lara Kent. When new threats begin to rise across Kansas and Metropolis, Clark reluctantly steps out of retirement—not as Superman, but as a mentor. As his powers wane, he must teach his children how to balance their growing Kryptonian abilities with their humanity, guiding them to become the next generation of protectors the world needs.
