New surveillance video, obtained by TMZ Sports, includes the sound of a woman screaming and begging for help as Ezekiel Elliott's dogs allegedly attacked her in her own backyard last May.

The footage is part of a "dangerous dog" case file on Elliott's Rottweiler, Ace ... and, according to both witnesses and officials in court documents, it shows how Ace and two of the NFL star's other dogs escaped the running back's Frisco, Texas home on May 20 and terrorized neighbors.

The clips -- totaling around 90 seconds -- appear to show a landscaper leaving Elliott's side gate open while exiting the Dallas Cowboys player's property on May 19.

It appears the gate stayed open all night long and into the morning of May 20, when Elliott's dogs are seen walking through it and into the neighborhood.
