Eternal Sunshine of the Spotless Mind

Clementine unexpectedly appears at Joel's apartment late at night, around 3 AM, after having a few drinks. She accidentally damaged Joel’s car, which leads to a confrontation about their tumultuous relationship and her drinking habits.

During a visit to a flea market, Clementine expresses her longing to have a child, but Joel dismisses the idea. This disagreement escalates into a heated argument, leaving Joel questioning Clementine's readiness for motherhood.

Joel discovers that Clementine has undergone a memory-erasing procedure at Lacuna, a New York company, to forget their turbulent relationship. Heartbroken, he realizes she no longer remembers him or their time together.

In his heartbreak, Joel confides in his friends Carrie and Rob about his situation. He finds a disturbing note from Lacuna, reminding him that he should not contact Clementine anymore, which deepens his despair.

Devastated by the loss of Clementine, Joel decides to undergo the same memory-erasing procedure to forget her. He hopes this decision will provide him with relief from the pain of their relationship.

Upon arriving at Lacuna, Joel meets Howard, the owner and doctor, who provides few details about Clementine. Howard mentions her unhappiness, leaving Joel to reflect on the impact of their relationship.

Before the procedure, Joel records a heartfelt message detailing their relationship’s highs and lows. He also gathers personal objects that relate to Clementine, which will be used to map out his memories.

As the procedure begins, Joel recalls their first encounter at the beach in Montauk. Despite being with another woman, Joel is immediately drawn to Clementine's vibrant personality, marking the start of their complicated love story.

While Joel's memories are being systematically erased, he starts to experience key moments with Clementine. He fights against the erasure as he relives these cherished memories, realizing he prefers to remember them.

As Joel's memories near deletion, he finds himself back at the beach where he first met Clementine. In a moment of clarity, she urges him to find her again in Montauk, hinting at their destined connection.

Post-procedure, Joel wakes up with all memories of Clementine erased. He inexplicably feels drawn to Montauk on Valentine's Day, where the weather reminds him of their first meeting.

In Montauk, Joel spots Clementine wearing her characteristic orange sweatshirt. Despite his hesitation to engage her, fate brings them together as they find themselves on the same train back home.

Once they reach Boston, Joel offers Clementine a ride, which leads them to her apartment. Their chemistry sparks again, and they share a spontaneous date by the frozen Charles River.

Ultimately, Joel and Clementine listen to their Lacuna records and confront the painful truths of their shared memories. They express a mutual desire to try again, signifying a hopeful renewal of their relationship.
