Eve of the Daleks

The final new years special. Daleks attack in Manchester New years day 2021. The TARDIS is broken after flux, the exterior is cracking creating a time loop in which Sarah a Nick keep dying to Daleks over and over, The Doctor must save them. They blow up the building with explosives from Nick's storage locker which resets the TARDIS.

Nice convoluted plot after the convoluted Flux arc.
