Nothing in Saoirse's life is going right. Her mother has dementia, her father wants to get remarried, she broke up with her girlfriend, and she's lost her best friend. As a result, she decides to swear off relationships for good until she meets mischievous and rom-com loving Ruby. So, Ruby proposes a loophole in Saoirse's no-relationship policy: a no-strings attached summer fling where they go on every cliché rom-com date they can think of. Saoirse agrees, but she soon finds herself falling hard for Ruby and fears she won't be able to end it when fall comes.
