Chris and Tina set out on their long-awaited road trip, despite the disapproval of Tina's mother. The trip signifies a fresh start for the couple, though underlying tension simmers due to past events involving their dog, Poppy.

During their stop at the museum, Chris encounters a man littering and confronts him. This initial conflict serves as a precursor to the escalated violence that will follow.

In a shocking turn of events, Chris intentionally runs over the litterer, masking his true intentions as an accident. This event marks the first of many moral downfalls in their journey.

At a caravan park, Chris and Tina meet Janice and Ian, who own a dog resembling Poppy. Chris's jealousy ignites when he learns about Ian's writing success which leads to further turmoil in his relationship with Tina.

Overwhelmed by envy, Chris violently confronts Ian during a solitary walk. He bludgeons Ian with a rock, steals his camera, and pushes him off a cliff, committing another heinous act.

Tina discovers the photos taken by Ian on the stolen camera which leads to a confrontation with Chris. In a chilling moment, Chris confesses to Ian's murder, and to his surprise, Tina accepts him wholeheartedly.

While walking in a National Trust park, a confrontation occurs when Banjo defecates, leading to an altercation with an angry tourist. Chris manipulates Tina into falsely accusing the man of assault, inciting further violence.

In a fit of rage, Chris brutally kills the tourist, showcasing his increasingly erratic behavior. This act deepens their spiral into moral depravity as they continue their journey.

At another caravan park, during dinner, Tina witnesses Chris kissing a bride as part of a dare, which drives her into a murderous rage. In a shocking act, she pushes the bride down a hill, killing her.

The morning after the bachelorette incident, Tina feels betrayed by Chris and decides to leave. Chris attempts to confess his crimes but is met with rejection, highlighting the disintegration of their relationship.

Chris wakes up to find Tina speeding down the highway in a fit of anger. In a tragic event, she runs over a jogger, leading Chris to rationalize his past actions as justified compared to hers.

After disposing of the jogger's body, Chris and Tina camp near the picturesque Ribblehead Viaduct. They are confronted by a sudden hailstorm which drives them back into the safety of their caravan.

Martin arrives with his dog, Banjo, leading to a clash over the moral quandaries surrounding their actions. As tensions rise, Tina reacts fiercely to a trivial argument, pushing Martin's caravan off the cliff with him inside.

In a moment of emotional turmoil, Chris and Tina share a brief connection before Chris takes drastic action by setting their caravan on fire. This act symbolizes their deep-seated chaos and destruction.

As their journey reaches its pinnacle, Chris and Tina reflect on their tumultuous holiday. In a heart-wrenching climax, Chris falls to his death from the viaduct after Tina inadvertently lets go of his hand, marking the end of their dark escapade.
