The TARDIS all but discharges, in a parallel world like our own, so the Doctor, Rose and Mickey find some time to have a roam (while the TARDIS repowers, phew!). Micky goes his separate way and bumps into his double, while the other two are hired help at a party where there's trouble (although Micky is in a spot of bother too). The Cybermen surround the place and things are looking bad, not just for our three travellers, they're at Rose's mam and dad's (in a parallel world sense at least).
