Joseph (Ben Whishaw) is a quiet, unassuming man who works in the security team at Stanstead airport. Isolated and lonely, his birthday goes unnoticed by his boisterous colleagues, and is celebrated in a rather begrudging fashion by his controlling parents. Yet, beneath his meek façade, Joseph is reaching his breaking point and is no longer willing to endure a life devoid of emotion and meaning. After an impulsive act of rebellion, Joseph unleashes a wilder version of himself. He is propelled on a reckless, hedonistic, and dangerous odyssey through London in an attempt to experience what it feels like to be alive.
