As Mother's Day approaches, Papa Bear and the cubs do their best to surprise Mama with breakfast in bed and a gift, and Mama does her best not to ruin the surprise.
Annoyed that Sister Bear always beats them at baseball and other "boy" type activities, her brother and the other male cubs try to exclude her from their new club.
Sister Bear does not like gym, so when she hurts her ankle she uses it as an excuse not to participate even when it feels better. But she learns that gym is very important and even starts to like it.
To keep busy during the summer, Brother and Sister Bear go to work for Farmer Ben, who promises to pay them what he earns for one corner of his corn crop at the end of the season.
