Set in the London tech scene, Iris, a neuroscience major, begins to explore the transactional world of The Girlfriend Experience and quickly learns that client sessions provide her with a compelling edge in the tech world.

Iris and her co-worker start working on an AI project that mirrors human emotion. Meanwhile, new clients provided by a high-end escort agency, leave Iris with a wealth of behavioural data.

Iris gets better at simulating the perfect girlfriend experience for her clients; simultaneously at NGM, Iris and her co-workers start training the AI model with new, simulated sets.

Iris' client relationships seem increasingly uncanny, and advice from Tawny isn't what Iris was hoping for. Her father's illness catches up with Iris in undeniable ways.

Iris can't keep her two worlds separate anymore, which comes with unwanted consequences. Iris realizes she's in a position of power, while simultaneously having lost all control.

Buying time, Iris escapes the messy leftovers of her double life and takes time off-grid. Georges, a former client, takes Iris into his world. Reality, however, has a way of catching up.

Cassie is back with a vengeance, taking her work to the next level. Iris' secrecy around the project puts a dent in her relationship with Hiram and their collaboration around Emcee.

Having family in town brings up complicated feelings for Iris. Tawny feels bad about how things played out with The V. Afraid to face her own truth, Iris realizes she needs to switch gears.

Having lost all sense of perspective, Iris confides in Christophe. He in turn opens up a part of his world. Little does Iris know; the encounter will leave her shaken to the core.

Struggling to recover from betrayal, Iris is willing to take a radical leap once again. Iris needs to confront one more person before making a fateful decision.
