Doctor Who S8 Ep 5 - F2F & M2F Transformations

Series 8 Episode 5 Time Heist
The group work their way back into the main floor of the bank, with Saibra — whose mutation allows her to shapeshift into any living thing she touches — using the identity of a bank customer whose DNA had been included in the case to get them in. The Doctor and Clara are surprised when the guards turn out to be Saibra and Psi - the disintegrators were really teleporters linked to a ship in orbit.
