Butterfly Kiss

In the desolate motorways of Lancashire, Eunice, a bisexual serial killer, sets out on a chilling quest. She is in search of a mysterious woman named Judith, frequently inquiring if the cashiers she encounters share her name.

After a fruitless search at a filling station, Eunice finds herself dousing in petrol outside. Miriam, the cashier, rushes out and invites Eunice to stay the night at her apartment, which is also home to her ill grandmother.

At Miriam's apartment, Eunice reveals her body adorned with chains, piercings, and tattoos, seducing Miriam. However, the next morning, Eunice leaves abruptly, writing 'you're not Judith' on the mirror with toothpaste.

Eunice hitches a ride with a delivery driver, Tony, whom she seduces. In a shocking turn, she murders him while they are intimate, stealing his van afterward.

Abandoning her grandmother, Miriam decides to pursue Eunice. She catches a ride with Mr. McDermott, a friend, and they locate Eunice in the stolen van, joining her on her dark journey.

Upon arriving at a forest, Eunice shows Miriam the corpse of Tony. In a bizarre twist, Miriam offers to help Eunice conceal the evidence by dragging the body to bury it.

Eunice decides to abandon Miriam and goes to a nearby diner where she meets waitress Angela. After inviting her to sit, Eunice returns to Miriam, who is glad to see her back.

While having breakfast at a filling station café, Eunice tries to send Miriam home. However, Miriam remains steadfast and refuses to part ways, demonstrating her commitment.

Eunice takes a detour to an amusement park, picking up two hitchhikers, Gary and his daughter Katie. Meanwhile, Miriam uncovers Angela's body hidden in the boot, prompting her to refuse further travel with them.

Eunice orders Miriam to find Gary when she spots Katie alone. After manipulating the situation, Eunice and Miriam leave, and Miriam wrestles with the belief that she has murdered Katie, only to find her later in the car.

On a bridge, Eunice admits she couldn't kill Katie only because the girl wouldn’t look at her. Cursing her fate, Miriam tries to console Eunice, aspiring to help her become a better person, but Eunice coldly rejects the possibility.

The duo arrives at a truck stop where they meet Robert, a philosophical truck driver. Eunice proposes a sexual encounter with Robert involving Miriam, leading to dangerous consequences.

As Robert engages with Miriam, Eunice returns and, enraged by the situation, murders Robert with a headlight. They steal his lorry to continue their chaotic journey.

After a brief interaction at another filling station, Eunice's rage is triggered when a cashier named Judith does not recognize her. Miriam steps in to prevent Eunice from causing a scene.

Eunice guides Miriam to a remote area where she expresses her desire to become a sacrifice. Together, they march into the sea, and as the tide rises, Miriam is compelled to drown Eunice, culminating in a tragic ritual.
