It’s all fun and games at a raucous teen party until two people are brutally attacked with a pair of scissors and the Major Crimes unit has their hands full picking the culprit out of the crowd. Provenza meets someone (recurring guest star DAWNN LEWIS – A Different World) who will change his life. Guest stars include SPENCER DANIELS (Mom), JOEY POLLARI (The Inbetweeners) and TIFFANY BOONE (The Following), with recurring guest stars KATHE MAZUR and RANSFORD DOHERTY as DDA Hobbs and CI Kendall, respectively.

A mysterious woman, Rachel Dunlevy (BLAIR BROWN - "The Days and Nights of Molly Dodd"), visits the Kents and claims to be Clark's mother, prompting them to finally tell Clark what happened after they discovered him in the cornfield that fateful day. Clark learns why his father hates the Luthors, how his adoption was arranged--and who else has rescued Lex from death.

After discovering that Lionel has secretly installed video cameras in the mansion, Lex hires thugs to put surveillance devices in Lionel's Metropolis office. However, the situation gets out of control when Lionel and Martha surprise the interlopers and are taken hostage. Desperate for a way to save his mother without exposing his powers, Clark must access the office from an adjacent tall building--if he can make the leap in a single bound.

While dirt-biking with Pete, Clark falls into a cave and discovers two hidden treasures: ancient Native American inscriptions that hold the key to his identity and a beautiful girl whom he believes to be his soul mate. Desperate to preserve the writings, Clark pits father against son by enlisting Lex's help in stopping Lionel's construction crew from demolishing the cave.

After Lionel is shot and wounded, Jonathan is arrested. But Clark and Pete perform their own crime scene investigation and realize that more than one person had the opportunity and motive to harm Lionel--including Lex. Meanwhile, Lana becomes suspicious when her lawyer father, Henry (recurring guest star PATRICK CASSIDY), mysteriously refuses her request to defend Jonathan.
