In the vibrant backdrop of a Phoenix wedding celebration, Scott (Justin Long) and his new bride Kristin (Jess Weixler) remain blissfully unaware of the tragedy that looms ahead. Their joyous occasion takes a dark turn as Scott's best man, Lumpy (Tyler Labine), spirals into a drunken stupor, determined to wreak havoc on the festivities, much to Kristin's growing frustration. As the night progresses, Lumpy's recklessness culminates in a tragic accident when he falls onto a cactus, resulting in his untimely death. The couple is left shattered by the news and now must navigate the painful task of arranging for his return to Minnesota for a proper burial.
Simultaneously, in the quaint town of Northern Minnesota, 15-year-old Ramsey Anderson (Addison Timlin) grapples with her turbulent family situation. With a mother ([Frances O'Connor]) struggling with addiction and a menacing stepfather ([Evan Jones]) who cooks meth, Ramsey finds herself in precarious predicaments. Life takes an alarming turn when she blackmails the local priest ([Michael Landes]) after discovering him in a compromising scenario, using the leverage to secure groceries for her family.
As circumstances at home worsen, Ramsey resorts to shoplifting cold medicine from a drugstore, only to be caught by the same priest who had previously aided her. This series of unfortunate events sets in motion a chain reaction that irrevocably changes the course of her life.
As Scott and Kristin delve deeper into Lumpy's mysterious background, they are propelled into a convoluted journey of discovery. Their initial search through phone records ends in silence, prompting them to visit his former law school and workplace. Here, they uncover troubling revelations: Lumpy had abruptly exited both his studies and job due to embezzlement allegations, leaving a trail of confusion and intrigue behind him.
Determined to unearth the truth, Kristin encourages Scott to confront the reality of Lumpy's enigmatic ties to someone significant. This confrontation reaches a boiling point during a strained Christmas dinner that prompts Scott to seek deeper answers about Ramsey's connection to Lumpy.
Through a sequence of revealing flashbacks, we learn that Lumpy's connection to Ramsey was forged ten months prior, when he unexpectedly knocked on her door, seeking passage through her family's property for ice fishing. A fateful fall through the ice and a heartfelt rescue initiated an unlikely friendship that would ultimately intertwine their destinies.
Arriving at Ramsey's home to inform her of Lumpy's death, Scott and Kristin are met with resistance as Ramsey, in distress, requests they leave. Retreating to a local hotel, Scott confides in Kristin about his recent professional setback, revealing that Lumpy had even funded their honeymoon.
However, hope reignites when Ramsey appears at their door the following morning, tearful and seeking a ride to Minneapolis for Lumpy's funeral. In a shocking revelation, she confides that she is pregnant with Lumpy's child, urgently yearning to escape her troubled life. When they agree to take her to her mother's house for permission to leave, an encounter with Ramsey's gun-toting stepfather leads to a tense standoff.
In a powerful and emotional turn, Ramsey's mother recognizes her daughter's opportunity for liberation and, with tears, offers her blessing along with a small amount of money, allowing her daughter to pursue a brighter future.
As the weight of Lumpy's death settles in, an intense exchange ignites between Ramsey, Kristin, and Scott when Ramsey reveals a harrowing truth: Lumpy had concealed a life-threatening secret from them. This confrontation culminates in an emotional outburst as Ramsey departs, leaving behind unresolved feelings.
At Lumpy's funeral, Ramsey delivers a poignant eulogy brimming with personal anecdotes about their relationship. She shares that Lumpy remained a true gentleman, never succumbing to physical desires, a sentiment further emphasized by Lumpy's mother presenting her with a heartfelt bequest to aid in her education.
As attendees disperse from the ceremony, Ramsey speaks with Scott's boss, Rick ([Sasha Andreev]), leading to a breakthrough that restores Scott's job. The following day brings more good news: Ramsey learns that her mother has ended her toxic relationship and is relocating, paving the way for Ramsey to stay with Scott and Kristin as she rebuilds her life.
In the end, as plans for dinner are set, Scott privately inquires about Rick's reinstatement, and Ramsey, with a knowing smile, deflects his curiosity, leaving the door open for future revelations. With the credits rolling, the trio is seen preparing for an evening filled with promise, signifying new beginnings while carrying the bittersweet memories of Lumpy's far-too-brief life.
