After an explosion Lana finds herself getting visions of a serial killer...and his next target is Chloe. Meanwhile Lex and Roger look further into the meteor shower and determine that something besides meteors hit Smallville that day.

Checking out a crater in a cornfield, Clark and Lana discover a baby with no parents and take him back to the Kent farm. However, when the baby, Evan, ages from a newborn to a 7-year-old in less than a day, it becomes clear he is aging at a rapid rate and they turn to Lex for help. Meanwhile, Genevieve suspects Lex has the Chinese Kryptonian artifact and orders Lionel to either recover it...or risk putting Lex in danger of his life.
