What happens when you throw a former combat soldier into one of the most dangerous prisons in Mexico? He either becomes prey—or he becomes a panther.

For Gal Shefrau, a former Israeli special-ops commando, Mexico was supposed to be a fresh start. A high-risk job as a bodyguard in Mexico led to an even riskier obsession: high-stakes gambling, underground power struggles, and the kind of self-destruction that comes with constantly living on the edge. But as one bad bet followed another, he could feel his options slimming. And what is a man to do when he’s in the crosshairs of Mexican cartels and all the lawful options have run out?

After a bank robbery and a high-speed police chase, Shefrau found himself locked inside Cadereyta—one of Mexico’s most notorious and violent prisons—a place where survival wasn’t a right, but a privilege earned in loyalty. And blood.

For over three years, Shefrau fought to stay alive in a world ruled by cartel bosses, corrupt guards, and prison politics as ruthless as any battlefield he encountered. But just when he hit rock bottom, his military instincts kicked in. Alliances were formed. Respect was commanded. And before he knew it, Shefrau didn’t just survive—he adapted.

Becoming La Pantera is a raw, unfiltered true story of crime, addiction, and the high price of power, told from the inside. It’s a journey into the darkest corners of human nature—where one man had to lose everything to discover the beast within.
