Rigsy is a young offender who was caught illegally drawing graffiti on public property, so he was ordered to remove it through community service. However, Rigsy meets the Twelfth Doctor’s companion Clara Oswald and the pair discover that the graffiti is coming to life! The murals are living creatures called the Boneless, that suck people into the walls (Flatline). The Doctor is able to defeat the Boneless from within his shrunken TARDIS. The Doctor and Clara meet Rigsy again when he calls them for help about a tattoo that suddenly appeared on the back of his neck (Face the Raven). The Doctor realises that this is a Chronolock counting down to Rigsy’s death. Clara, Rigsy and the Doctor find a hidden trap street in London, where they encounter Ashildr again. Ashildr/Me put the Chronolock on Rigsy for a crime that he couldn’t remember committing. Clara agrees for Rigsy to pass the Chronolock onto her, but this kills her instead.

The TARDIS’s exterior dimensions are shrunk by an unknown force. The Twelfth Doctor and Clara climb out of a miniaturised TARDIS and discover that they have landed in Bristol. Clara walks off briefly but returns to find that the TARDIS is now tiny with the Doctor stuck inside! Nearby, humans are being sucked into walls by terrifying two-dimensional creatures called the Boneless. The Boneless hide in the walls and their human victims appear on the walls too as murals. Clara takes charge and befriends a boy called Rigsy who is cleaning up his graffiti as part of community service. The Doctor creates a device called a 2-DIS to return objects flattened by the Boneless to their original three-dimensional state, and from three-dimensions to two-dimensions again. The Doctor realises what the Boneless are and he helps Clara, Rigsy and the other community service workers to escape from the Boneless in a train tunnel. The Doctor’s TARDIS reverts to siege mode to avoid being hit by a train. Clara positions the cube siege TARDIS behind a door and tricks the Boneless into secretly pouring their power into the siege TARDIS. The TARDIS returns to its normal size and the Doctor uses his sonic screwdriver to banish the remaining Boneless back to their universe of only two dimensions. Rigsy would later meet the Doctor and Clara again in Face the Raven.

The Twelfth Doctor and Clara receive a phone call from their old friend Rigsy who they previously met in Flatline. Rigsy has discovered a Chronolock tattoo on his neck, a number that is counting down. The Doctor decides to fly the TARDIS above London to trace the person who planted it on Rigsy. The Doctor, Clara and Rigsy eventually find the entrance to a Trap Street, a refuge for alien refugees hidden behind a perception filter. The Mayor of the Trap Street is the immortal Ashildr, whom the Doctor and Clara previously met in The Girl Who Died and The Woman Who Lived. Ashildr has become ruthless and unmerciful over the centuries and is happy to condemn petty crimes like theft to a death sentence. Rigsy is accused of murder and so Ashildr put the Chronolock (a countdown to execution) on his neck and wiped his memory. In private, Clara stupidly asks Rigsy to pass the Chronolock onto her. However, when this is revealed to Ashildr she says that the Chronolock cannot be stopped. A tearful Clara says goodbye to the Doctor before she too is killed by the Quantum Shade raven, which flies into her. The enraged Doctor is handed over to Ashildr’s employers, who Ashildr refuses to name. Rigsy paints a mural of Clara on the TARDIS.
