Target

Soo-hyun (Shin Hye-sun), a recently moved office worker, buys a used washing machine through a second-hand app but discovers it's broken. Her comment to the seller, calling them a con man, inadvertently foils their hunt for a new victim, making Soo-hyun their next target as she receives ominous phone calls and strange visitors. Detective Joo Cheol-ho (Kim Sung-kyun) investigates alongside her after a trip to the seller's address proves deadly serious.
