Four in One is the umbrella title for a wheel series broadcast in the United States on the NBC television network as part of its 1970-71 schedule in the Wednesday 10 PM Eastern time slot.
Four in One consisted of six episodes of each of four dramatic series: McCloud, San Francisco International Airport, Night Gallery and The Psychiatrist.
All six episodes of each program were run in order; then all were rerun interspersed with each other with a different series being shown each week.
The other two elements, San Francisco International Airport and The Psychiatrist, were cancelled.
