Writer-director Radnor stars as Jesse, a 30-something who returns to his alma mater for a favourite professor's (Richard Jenkins) retirement party, and ends up falling for a precocious young student (Elizabeth Olsen).
Allison Janney and Zac Efron also star as Jesse's jaded former professor and an oddball student respectively.
