Clark is arrested and his family faces a civil lawsuit after the teen defends Lana by hurling an unruly college student onto the hood of an oncoming police car. Elsewhere, Helen's former boyfriend arrives in Smallville and causes trouble for Lex by filing a false assault charge against him.

Lana thinks she sees the ghost of a childhood friend who died years before when she's visited by a 10-year-old girl, so Clark sets out to find a logical explanation for the incidents. In other developments, Lex prepares for his wedding by meeting with an event coordinator; and Jonathan begins building a crib in anticipation of the new baby.
