"Mods and Rockers - A Love Story" follows David Stevens, leader of The Ace Faces mod gang, and Sharon Mitchell, sister of a Thunder Boys rocker, whose forbidden romance begins during the infamous Brighton riots of May 1964. When their eyes meet across the battlefield of tribal warfare, both recognize something deeper than the hatred that divides their worlds.

David, a sharp-dressed nineteen-year-old from Hackney, leads his scooter-riding gang with intelligence and style. Sharon, seventeen and fiercely independent, feels trapped by the violent rocker culture that defines her brother Tommy's world. Despite the danger, they begin meeting secretly at The Blue Note jazz club in Soho, discovering shared dreams and questioning the meaningless tribal conflicts that govern their lives.

Their clandestine romance blossoms over Wednesday evening conversations about books, music, and hopes for a different future. But when Tommy discovers Sharon's betrayal, he issues an ultimatum: choose family loyalty or love. The revelation triggers a vicious gang war between The Ace Faces and The Thunder Boys, with both David and Sharon caught in the crossfire.

Facing escalating violence and rejection from their tribes, the young lovers make a desperate choice: they elope to Manchester, abandoning everything they've known for an uncertain future together. Living in poverty, they struggle to build a new life while Sharon discovers she's pregnant. Their son James is born in February 1965, cementing their commitment to each other and their new identity as the Stevens family.

As the cultural landscape shifts toward the psychedelic movement of the mid-1960s, David recognizes a business opportunity. Using Sharon's sewing skills and his understanding of youth culture, they create "Cosmic Threads," a company producing psychedelic clothing that captures the spirit of the emerging flower power movement.

By 1967's Summer of Love, their business has become hugely successful, boutiques across Britain
