From Amazon Prime:

ZOE tells a tale of forbidden love between an engineer and a robot. ZOE (Léa Seydoux) and COLE (Ewan McGregor) are colleagues and veiled lovers at a lab working to perfect romantic relationships. But their
relationship is threatened when Zoe discovers the truth about their relationship, sending them into a spiral of confusion, betrayal and the most intense of human emotions, love.

From Amazon Prime you can stream this 1 hour 43 minute complete film.

Rather than a sci-fi story, this film centers on the divide between human emotions and manufactured emotions injected into a robot body indistinguishable from a human body. Can that divide ever be genuinely crossed?

In addition to the relation between Zoe and Cole,  there is a relevant third party Ash, also a robot (played by Theo James who plays Sidney Parker in “Sanditon”).  Imagine being sentient enough to realize you exist but can be “turned off” at any time.

Consisting almost entirely of discussions about emotions and the possibility of happiness, do not expect any action sequences.
