Douchebag

Sam Nussbaum lives in Los Angeles with his fiancée Steph, presenting a steady life shaped by his environmentalism. Yet a two-year rift with his younger brother Tom lingers after a fight over their dog Angela and a memory Sam wants to bury. Steph senses the tension and begins to uncover the history Sam hides.

Steph meets Tom and learns there is a complicated history between the brothers. They vow to keep their rivalry at a low simmer so the wedding can proceed, signaling a fragile pact to move forward. Tom and Sam commit to working toward reconciliation with Steph watching closely.

Sam and Steph flip through Tom's fifth-grade yearbook and uncover Mary Barger, Tom's childhood sweetheart, at the center of his past. They decide Tom should invite Mary to the wedding as a way to smooth the road to reconciliation. The search reveals there are three Marys in California named Mary Barger, setting the stage for comic misidentifications.

In Santa Monica, the first Mary greets Sam with flowers, but the moment is awkward as she reads his intentions. The encounter exposes how easily misunderstandings can derail the brothers’ plan. Tom and Sam press on despite the hiccup.

The search continues to Palm Springs, where the second Mary works at a roller rink. She denies being Tom's childhood sweetheart but agrees to a spontaneous outing with him, and the evening hints at potential chemistry without a lasting match.

Steph stops at a tuxedo shop and discovers Tom was never properly fitted for the wedding. The practical flaw adds drama to the road trip and raises the stakes of the looming ceremony. The moment underscores how small details ripple into bigger tensions.

On the way to San Diego, the trio stops at a teahouse where Sam flirts with a patron named Sarah who slips her number to him. The moment fuels jealousy and unsettles the brothers’ fragile truce. Tom watches the scene unfold, unsure of how to respond.

During the drive, Sam breaks his vegetarian creed by eating a hamburger, a small act that crystallizes the deeper fractures with Tom. The act becomes a symbol of Sam’s self-confessed flaws and the widening rift between brothers. They continue onward, the road revealing more than it travels to reach San Diego.

The night wears on at a motel where they drink beer and talk, the room turning into a pressure cooker for honesty. Old wounds surface and the trip becomes less about the wedding and more about who they are. The shared space pushes them toward a reckoning.

The next morning Sam slips away to a party and ends up having sex with Sarah. Tom confronts him, demanding to know what happened between the brothers, and Sam confesses that Angela was a woman he found himself attracted to. The revelation leaves Tom betrayed, and Sam laments his own flaws.

Tom confronts Sam about the events, and Sam acknowledges that he is not a good person. The brothers freeze the moment but do not cut ties entirely, choosing to carry the truth forward while wrestling with forgiveness. The road trip continues with a heavier, more honest tone.

They decide to press on to pursue the final Mary—the true Mary Barger—yet Tom’s fatalism makes him think it might not matter, so they head back toward Los Angeles. Steph’s feelings shift dramatically as she questions the idea of marriage in light of the truth they’ve uncovered.

Steph declares she does not wish to get married, prompting Sam to reflect on his own need to change. He moves out and vows to keep a weekly garden ritual for Steph as a steady gesture of care. The journey leaves everyone with a sense of possibility even as they navigate the fallout.

Later, Sam visits Tom at an art gallery displaying illustrations from their road trip. The show becomes a quiet acknowledgment of their history and a sign that growth is possible. The film closes on a hopeful note about two brothers who are still connected and a future shaped by honesty.
