In the vibrant but modest music scene of Christchurch, New Zealand, a young Gary Thain discovers his deep connection to the bass guitar. Fueled by raw talent and a restless ambition, Gary's journey takes him halfway across the world to England, where he becomes the heartbeat of Uriah Heep, one of the most iconic rock bands of the 1970s.
The film explores Gary's creative genius, from crafting unforgettable basslines on legendary tracks like Stealin’ and Easy Livin’ to the electric energy he brought to every performance. At the same time, it delves into his struggles with the grueling demands of life on the road, personal insecurities, and the era's pervasive drug culture.
Through a mix of euphoric highs—like headlining massive venues and earning the adoration of fans worldwide—and harrowing lows, including a near-fatal onstage electrocution and worsening health, Gary’s story is both a celebration of a musical prodigy and a poignant reminder of the human cost of rock stardom.
