The Cowboy's Lullaby

Dr. Mike takes in Red McCall, a down-and-out cowboy, and his ailing half-breed infant child. McCall reaches the end of his rope trying to care for his baby, so after robbing Loren's store, he leaves the baby in Michaela's care, sensing she could find a suitable home for his child. Dr. Mike's attempts to find a home for the baby prove futile.
When she travels to a remote cabin to check on the health of it's owner, she finds him badly mangled from a bear attack. Her horse is frightened off by the bear, and she's marooned in the cabin until Sully shows up looking for her. They narrowly escape being the rabid bear's next victims.
After returning to town, Dr. Mike decides she'd rather raise the child herself than turn him over to an orphanage. However, Sully locates Red and convinces him to keep the child.
