Lee, a dedicated yoga instructor, takes a temporary assignment house-sitting for a client alongside her husband Tim, a gym teacher, and their energetic 3-year-old son, Jude. As they explore the secluded property, Tim stumbles upon a gun and a bone in the backyard. Though curiosity tempts him to dig deeper for hidden secrets, Lee dissuades him, suggesting it might lead to trouble.
When Lee and Jude decide to spend the weekend with her parents, Tim seizes the opportunity to invite a few friends over, including Ray](/actor/ray), Phil, Adam, and Paul. Their casual gathering takes a turn when they, inspired by a few drinks, collectively agree to excavate the backyard. They quickly unearth another bone and a license plate. As the evening progresses, Phil, feeling uneasy about their antics, leaves the party with Adam and Paul, while Tim's friend Billy arrives with call girls, Alicia and Max. Billy pairs up with Alicia, while Ray finds a connection with Max, but Tim remains fascinated with digging and discovers a shoe while the night winds down.
The following day, a concerned neighbor pays Tim a visit, cautioning him against further digging, revealing that the area once housed the "Chicano Hall of Fame." Shortly after, Max returns to claim her purse and joins Tim in his quest, only to uncover a plastic bag filled with bones. Meanwhile, Lee sets off to visit her sister, Squiggy, and brother-in-law, Bob, expressing her feelings of losing her identity post-motherhood.
Misunderstandings arise when Phil comes back to the house and sees Tim with Max, leading him to suspect infidelity. Tim and Max share a dinner where he opens up about his fears regarding his marriage with Lee, which he believes has fallen apart since having Jude. In a parallel narrative, Lee finds herself at a bar, where she meets Ben, who, after a scuffle, accompanies her to find Alicia to treat his wounds. Tensions flare when Tim and Max smoke marijuana, leading to another layer of complications.
As the evening continues, Tim confides his frustrations about his relationship to Max before Lee and Ben share a meaningful kiss at the beach, heightening the emotional stakes for both couples. Upon returning home, Tim’s unease pushes him back to the backyard, where he discovers a ring and what seems to resemble a human hand. He decides to abandon his digging endeavors, tossing the objects back into the hole and filling it in, before reconnecting with Lee, who patiently waits for him. They share a kiss, signaling a possible rekindling, and the next morning, they prepare to leave, collecting their belongings and getting ready to pick up Jude, reaffirming their commitment to family and each other amidst the unfolding mystery.
