In contemporary Liverpool, Jess and Elliot, two inseparable friends, find themselves caught in a whirlwind of indulgence, using parties as a way to escape the sorrow stemming from the enigmatic vanishing of Peter—Jess’s twin brother and Elliot’s beloved. Half a decade has elapsed since Peter went missing, yet Jess and Elliot remain hopeful that they will eventually uncover the truth behind his disappearance.

Elliot begins to move forward when he starts a new romance with Will, but this progress is halted when he learns that Will harbors his own sinister secrets. Simultaneously, Jess receives a message from someone claiming to be Peter, triggering a series of events that lead the friends to question whether Elliot is doomed in love or if he is being deliberately targeted.
