Agnes and Freja run a company that specializes in exposing unfaithful men by becoming the test themselves. Their methods are extreme, but in their eyes justified. They believe they're only revealing the truth: if the guys are going to fall for a flirt anyway, why not let them fall completely? But when they encounter the first guy who doesn't take the bait, everything is put at risk. Agnes cannot accept his rejection, and a moral transgression creates a rift between her and Freja. Soon, they face a crossroads where friendship and justice collide. The Boyfriend Testers is a comedy about friendship, betrayal, and doing the right thing by doing everything wrong.

A woman is blindfolded and whisked away by friends for a birthday celebration. When a voice from the past resurfaces, the line between surprise and trap quickly starts to blur.
