Smallville :

Clark and Lex are mystified when the Luthor mansion is robbed by burglars who seem to have the ability to walk through walls. Several jocks from the high-school have been infected by meteor-affected tattoos.

Lex's curiosity becomes desperation when he discovers that the thieves have stolen evidence of his secret project. Clark wonders if his father's suspicions that Lex is deceitful have been correct. Meanwhile Whitney joins the two of them to help fight the thieves.
