A new mother showed her newborn how to be a hero.
Frances Lonergan soaked up the Cape Cod sun on Dowses Beach in Osterville, Massachusetts, during a family vacation when a man's desperate cries for help snapped the serene scene.
"The victim, unfamiliar with the abrupt drop-off and strong current in the channel, had begun yelling for help as he struggled to reach the surface," Barnstable Police said on Facebook.
Bystanders called 911, but Lonergan did not wait.
