Description：Late at night in Spain, a middle-aged man ran in panic through the jungle and was eventually hit and seriously injured by a speeding car on the road. The police's initial investigation revealed that this man was a morgue guard and he must have seen some horrific scene before the accident. After further investigation, it was discovered that a body was missing from the morgue that night. The body was named Maca Villaverde (Belen Rueda), a powerful business woman who died of a heart attack shortly after returning from Los Angeles by plane that afternoon. The police contacted Maca's husband, Alex (Hugo Silva), who was accompanying his lover at the time. His indifference when talking about his wife forced people to question the relationship between the couple. Accompanied by the weird and murderous atmosphere, the truth gradually emerged.
