What Makes Us Different

Theatre Meets
Behavioural Science

Our immersive experiences go far beyond watching a show. Participants become part of high-stakes, interactive stories where every choice shapes what happens next. Active retrieval consistently outperforms passive review for long-term retention, Roediger and Karpicke (2006) showed testing increases retention by around 50% over re-reading, which is why our immersive theatre methodology drives behaviour change that traditional corporate training cannot match.

The Death of Jane Doe, immersive mental health experience by Sidestream

The Death of Jane Doe

An Immersive Exploration of Mental Health Stigma at the Workplace

Sidestream worked with Met Police Lewisham and The Innocence Project to create an experience that helped people face their own assumptions about mental health. As the story unfolds, participants meet people living with schizophrenia and antisocial personality disorder, and are asked: "Are you seeing the truth, or your own assumptions?"

"When else can you have an honest talk with someone living with a serious mental health condition, except through immersive theatre?"

The Accused

Sexism, Justice, and the Psychology of a Murder Trial

Set in a 1950s courtroom, participants step into the role of jurors in the trial of Ruth Ellis, the last woman to be hanged in the UK. Using real trial transcripts, live theatre, music, and film, the event explores how gender bias, media narratives, and double standards can distort our sense of justice. Over 600 people have taken part.

"A gripping and thought-provoking experience that made me reflect on how much, or how little, has changed for women in the workplace and beyond."

Leadership & Crisis Management

Top of the Cops

Punk, Protest, and Power: An Immersive Business Chaos Experience

Set in the gritty world of an underground 1980s punk gig, participants are thrown into chaos, where reputation, ethics, and control constantly collide. Rival bands clash, a family feud erupts, and an eco-protest threatens the night. Every decision shapes the story, showing how bias, values, and leadership style determine outcomes under pressure.

"An 80s punk gig as a masterclass in leadership and reputation management? Pure genius."

Auction decision-making experience

The Unfolding

Step into the Auction, Nothing is as it Seems

Participants enter a high-society auction led by the mysterious final will of a billionaire. Every bid carries hidden risks, and power quickly shifts. Drawing on psychology, economic game theory, and immersive storytelling, this experience explores how competition, collaboration, and human nature shape every decision. "Will you play the game, or will the game play you?"

"A high-energy, thought-provoking way to explore bias, decision-making, and what it really means to win."

Energy strategy simulation
Resilience & Strategy

The Sellafield Simulation

A High-Stakes Resilience and Strategy Ecosystem

A week-long simulation where participants step into the roles of government regulators, nuclear experts, NGOs, investors, and trade unions. Designing a sustainable energy transition for the Sellafield region, teams face a nuclear leak, a political shake-up, live negotiations, and an in-game currency (ISOTOPES) that measures influence and reputation.

"The closest thing to real-world business diplomacy I've ever experienced."

AI regulation simulation
AI & Future Strategy

Future-Proofing the Entertainment Industry

A Scenario Week on AI Regulation

Participants take on the roles of streaming platforms, film studios, AI developers, unions, and ethics groups, negotiating new AI rules in a fast-paced, competitive environment. Using TOKENS (an in-game currency), teams book meetings, form alliances, and win regulatory approval. The result: a realistic AI governance framework shaped by real stakeholder tensions.

"Brilliantly designed, it pushed us to think critically, adapt quickly, and understand the real pressures of AI governance."
