The Collector and a murder

As a full-time father, a collector of rare puppets, and as a puppeteer for a living, Miguel O'Hara has seen his fair share of hard times. But nothing brought him more joy when his daughter, Gabriella, started showing interest and wanted to learn about puppeteering.

However, upon purchasing a puppet in poor condition and restoring it, something clicks in Miguel's mind that this broken doll is holding a deadly and cruel secret. And now his daughter doesn't want to let go of it.

What secrets does this puppet hold? What is it trying to show him?
