"Margot" (Michelle Williams) encounters the hunky "Daniel" (Luke Kirby) on a plane after he spots her using some interesting tactics to get onto the priority boarding list. They hit it off pretty quickly and on landing share a cab to their homes - it turns out that they are all but next door neighbours. Now she is very happily married to "Lou" (Seth Rogan) but I challenge anyone married or otherwise not to find the charismatic Kirby a bit of a distraction. Not looking for change, what now ensues is a gently evolving romance that shies away from sentimentality but focusses more on human nature....
