In this 2021 documentary, we follow the story of a filmmaker and his fiancée as they explore alternatives to monogamy in the year preceding their wedding day. The pair enter into a polyamorous relationship, a decision that reaches unforeseen conclusions.

Jan Oliver 'Ollie' Lucks is a filmmaker and a self-described 'sexual underachiever.'

With less than a year until their wedding date, Lucks and his fiancée, Zoe Marshall, decide to engage in alternatives to monogamy.

In There's No I in Threesome, which premiered at the 2021 Sundance Film Festival, Lucks and Marshall explore whether monogamy truly is for everyone.

The pair begin with an open relationship, but quickly transition into polyamory.

Over the course of the documentary, Lucks and Marshall explore how modern couples can investigate experimentation with third parties, and the emotions that come with it.
