Twins Oakley and Ellis Garrison use their late father's ID to rent an AirBNB in Ocean City, MD for Senior Week, where high school grads celebrate childhood emancipation. When their first night spirals into a party and eviction looms, Oakley recruits local drug dealer Barton, who eerily resembles their dad, to pose as him. What starts as a desperate, psychedelic cover-up transforms into an emotional confrontation full of grief, siblinghood, and the bittersweet impermanence of youth.
