Los crímenes de la carretera

One night, Michael Fitzgerald discovers a dead girl in her bathtub when he returns from the supermarket. Next to her corpse is a sparrow feather. Terrified, he calls the police, who question him about the victim, Alyssa Tepper, whom he claims he does not know. Detective Dobbs and FBI Agent Gimble join forces in what looks like a simple murder: when photos of Michael kissing Alyssa come to light, he is immediately arrested, but within hours another victim appears with the same pattern: a sparrow feather placed next to the body. When more appear, not only in Los Angeles but throughout the country, it is clear that they face a new serial killer, which they nickname Birdman.
