[4] The film follows the unexpected friendship that develops between Adam, a man whose husband surprises him with online Spanish lessons, and his teacher, Cariño.

When Adam begins to panic Cariño helps to calm him down by showing him the gardens near where she lives, eventually lulling him to sleep.

Adam prefers that they talk candidly as they have in the past, but Cariño insists, wanting to maintain a professional relationship.

The next morning, Cariño records a message apologizing for the late call and canceling their future lessons as she is dealing with personal issues; however, she deletes it without sending it.
