The PJ attends to the murder scene of Pauline Garcia who has been run over and crushed by her own car. The team is happy to know that a witness may have met the murderer, but unfortunately they find out that she is blind. Pauline was an accomplished ice skater, selected to participate in the following Olympic games with the national team so the first investigations lead Kadarec and Alvaro to the ice rink where she used to train to interrogate her possible rivals.
