Starring in gay porn was never on Ed's bucket list. He's straight, he's not an exhibitionist, and he has a decent career in security.

If having gay sex in front of a camera is the way to digging himself out of this pit, then he's willing to be filmed for that money shot. But when he meets Glenn, the charismatic CEO of a gay porn production company, Ed finds himself falling into something much deeper than financial debt. Now, Ed is coming for the money...but will he be staying for Glenn?
