Sis (Marian Swayne) is an orphan who doesn't win any friends at the local Sunday school benefit because she's a poor farm girl and the rest of the kids are townies. But Sis has ambitions to be a stage actress so she runs away to the big city. She works as a drudge in a vaudeville boarding house, where she meets an actor, Jim (Hugh Thompson). She helps him rehearse, and as a result learns the leading woman's role word for word. The rest can pretty much be guessed -- the leading woman can't go on, and since the cast is apparently lacking in understudies, Sis gets to go on in her place. She's a sensation and winds up with Jim, who turns out to be the son of an old inmate of the orphanage. This type of storyline was as tired in 1917 as it is now.
