Detailed Summary

A Quiet Man with a Heavy Past

Dani (Mario Casas) is a quiet, polite man who has spent years caring for his dying father. After the funeral, he plans to start fresh: travel, clear his mind, and rebuild his life. He looks like the last person who would ever break the law. That’s exactly why Cross the Line becomes so unsettling. The film’s tragedy begins the moment Dani tries to move on.

Meeting Mila: The Catalyst

While preparing for his upcoming trip, Dani has a chance encounter with Mila, a reckless and unpredictable young woman. Their interaction turns into a night filled with bizarre behavior, drugs, and escalating violence. At first, Mila seems like a troubled soul who needs help, but the film slowly reveals that she is more dangerous than she appears.

A Single Decision Changes Everything

A violent altercation occurs at Mila’s apartment when her abusive acquaintance shows up. Dani, terrified and pushed into a corner, kills the man in self-defense. This moment is the psychological fulcrum of the story: the quiet, gentle Dani has just crossed a point of no return.

Covering Up the Crime

Panicked, Dani attempts to hide the evidence. Mila, seemingly experienced with chaos, pressures him to keep moving, to not think. The movie shifts from a suspense drama to a nerve-racking descent into guilt, paranoia, and moral collapse. The title No Matarás (You Shall Not Kill) echoes like a haunting prophecy Dani has already broken.

Movie Ending

As the night spirals out of control, Dani becomes mentally and morally unrecognizable. Mila pushes him into deeper criminal acts, and Dani learns she has been manipulating him all along. Everything from the drugging to the situations they “accidentally” fell into was designed to provoke him.

In the final sequences, police are closing in. Dani is covered in guilt and exhaustion. He is no longer the innocent son who cared for his father. He decides to confess. The ending shows Dani being arrested while looking emotionally destroyed, yet strangely at peace. He finally accepts responsibility, choosing truth over survival, even though it means losing everything. The final message is clear: once you cross a certain line, you can’t go back, but you can still choose who you become afterwards.
