In Someone Else, Aaron Yoo plays Jamie, a straight-laced “country mouse” business student who is all work and no play, who comes to stay temporarily with his bright lights, big city cousin Will (Leonardo Nam). An extroverted playboy-type, Will tries to bring out the painfully shy Jamie – the results of which have entirely unexpected results in the psychological warfare department. Tensions between the two cousins – the result of a long unresolved incident between their fathers – boil up, and Jamie’s sense of his own identity undergoes some perilously fraught shifts.
