Netflix viewers can’t stop talking about Mrs Biggs, the gripping five-part true-crime drama that’s suddenly stormed into the streamer’s Top 10 more than a decade after its original release. Starring Sheridan Smith and Daniel Mays, this haunting, beautifully acted series revisits one of Britain’s most notorious real-life crimes — the Great Train Robbery of 1963 — but from a perspective rarely told before: that of the woman who loved one of its most infamous men.

At its core, Mrs Biggs isn’t just about the heist itself. It’s about Charmian Biggs (played with stunning emotional range by Sheridan Smith), a woman who falls in love with Ronnie Biggs (Daniel Mays), only to watch her life unravel as her husband becomes embroiled in one of the most talked-about robberies in British history. What starts as a passionate romance between two dreamers quickly descends into heartbreak, isolation, and impossible choices.

Smith’s performance has been hailed as “utterly compelling” — she won the BAFTA for Best Actress for this role — capturing Charmian’s transformation from hopeful young wife to disillusioned fugitive, torn between loyalty and survival. Daniel Mays, meanwhile, brings depth and vulnerability to Ronnie, portraying him not as a one-dimensional criminal, but as a man seduced by greed and a desperate desire to provide more than the world ever offered him.

Set against the backdrop of 1960s Britain and later Australia, Mrs Biggs is as much a love story as it is a tragedy. The production spares no detail in its period authenticity — from the smoky pubs of post-war London to the sun-drenched suburbs of Melbourne — immersing viewers in a world where moral choices blur, and every decision comes with a price.

Critics and audiences alike are calling the series “brilliant,” “unmissable,” and “emotionally devastating.” It’s being compared to Toxic Town and Baby Reindeer for its mix of realism and emotional weight, yet it stands apart for its heartbreaking intimacy and historical depth. While crime dramas often glorify the act itself, Mrs Biggs does something far more powerful: it exposes the human cost of ambition, love, and betrayal.

Now that it’s available on Netflix, a new generation of viewers is discovering what made Mrs Biggs such an acclaimed series when it first aired — and why it still resonates today. It’s not just about the Great Train Robbery. It’s about what happens when love collides with truth, when loyalty becomes a trap, and when a woman’s only way forward is to face the past that has already defined her.

Raw, emotional, and beautifully tragic, Mrs Biggs isn’t just a crime story — it’s a love story pushed to the edge of destruction. And for many viewers, it’s easily one of the most unforgettable dramas streaming on Netflix right now.
