After they leave their engagement party, Chloe (Allison Mack) and Jimmy (Aaron Ashmore) are abducted by a psychotic jeweler (guest star David Lewis) who was emotionally scarred by his wife's infidelity and is now kidnapping couples and subjecting them to a kryptonite-enhanced lie detector that shocks them if they lie. The abductor asks Chloe if she is in love with anyone else.
Meanwhile, in an effort to find Chloe and Jimmy, Clark (Tom Welling) and Lois (Erica Durance) pose as a couple and are kidnapped themselves, then asked how they feel about each other.
