The woman’s boyfriend had threatened to kill her, police say.

So as they drove to visit the boyfriend’s family, she told him she needed to use a restroom at a McDonald’s – then told an employee at the counter to call 911 and gave her the car’s license plate number, officials said.

The woman tried to place an order at the store in Lodi, California, according to the San Joaquin County Sheriff’s Office. But by that point the boyfriend was nearby and demanded she use the drive-through.

“Help me,” authorities say the woman mouthed to staff as the car went by the service window.

The help arrived.
