Ammar Kandil, Thomas Brag and Matt Dajer go on adventures that define the group's name: Yes Theory. They say yes to tasks that make them uncomfortable, and the difficulties they encounter lead to authenticity – which intensifies their friendship.

They film everything they encounter in their path and produce mini-documentaries for their Youtube Channel – attracting millions of viewers.

As soon as the conversation starts, Cal instantly feels like a friend to these best of friends.
