Doctor Who returns with a brand new companion for David Tennant's popular Time Lord. Martha Jones (Freema Agyeman), is a smart, sassy, and sexy medical student who encounters the Doctor when her present day London hospital is transported to the moon.

From the moment the Doctor walks into her life, he changes it forever. Their adventures include meeting William Shakespeare at the Globe Theatre in Elizabethan London, a nightmarish underground world of gridlocked cars and the return of the Doctor's sworn enemies, the Daleks, who have been hiding in 1930s New York with a terrifying plan for humanity.

Premieres Saturday, January 26th at 7pm et/pt
