Anna Gardner (Felicity Jones), a British exchange student attending college in Los Angeles, meets and falls in love with Jacob Helm (Anton Yelchin), an American student who returns her affections. After graduation, Anna decides to spend the summer with Jacob rather than return to the United Kingdom, unaware of the consequences of overstaying her F visa, which expired upon her graduation. After returning to London for a family engagement, Anna flies back to Los Angeles, where she is detained, denied entry, and deported to the United Kingdom by immigration officials.
