A one-night stand is secretly recorded in a tense six-part thriller adapted from JP Pomare's novel The Last Guests. Paramedic Lina (Aisha Dee) has a doting fiance, Cain (Chai Hansen), who occasionally makes a fool of himself. After one such embarrassing incident at a party, Lina enjoys a passionate hook-up with Dan (Josh Helman), who is staying in an apartment owned by her friends, Axel (Luke Cook) and Clare (Laura Gordon). Lina realises after the grubby fact that she has accidentally left her engagement ring in the flat and when she returns to collect the jewellery, she notices hidden cameras. Dan is equally shocked and they begin a frantic search for whoever installed the covert surveillance so they can destroy evidence of Lina's infidelity.
