Dates from ancient Greek times, where "deus ex machina" ("god from the machine") in a play referred to the act of lowering a god on stage using a cable device (therefore, a god from a machine) to decide in a dilemma and give fate a nudge, so to say.

These days, deus ex machina has the negative connotation of an utterly improbable, illogical or baseless plot twist that drastically alters the situation, as if the "deus ex machina" came down to give fate that little push.

Literally "God from the machine", Deus Ex Machina originally referred to Greek plays, where the "gods" would be lowered onto the stage in order to provide a quick resolution to the story. Today, Deus Ex Machina refers to any improbably and/or overly convenient character or mechanism that comes out of nowhere saves the character(s) from their doom.
