Description:  Incorporating the Xeraphin race into his TARDIS power system, the Master has won, but technical obstacles and a bit of sabotage from friendlies give the Doctor a bargaining chip for the lives of the hijacked and enslaved airline passengers and crews - with maybe, just maybe, some hope for the Xeraphin race as well.
