Bull, an aging biker recovering in the hospital, is comforted constantly by his loyal dog, Duke—the same dog who saved his life during a heart attack. When Bull’s estranged daughter Rachel arrives with police, she tries to take Duke away, claiming he’s dangerous and that Bull is unfit to make decisions. Her resentment stems from years of shame over her father’s biker lifestyle, which she believed ruined her childhood and reputation.

Bull breaks down, devastated, pleading not to lose his only companion. With help from hospital staff and Bull’s old biker friend Tommy, Rachel learns the truth: Bull sacrificed everything for her—even selling his beloved motorcycle to pay her college tuition—while she erased him from her life out of embarrassment. Realizing the pain she caused, Rachel finally sees her father not as a burden but as a loving, selfless man who always put her first.

Rachel admits her mistakes, abandons her attempt to take Duke, and slowly rebuilds her relationship with Bull. She learns to embrace who he truly is and even begins spending Sundays with him, her husband, and eventually her children—reclaiming lost time and love.

Months later, Bull is healthy, Duke still at his side, and Rachel proudly defends her father from judgment. Their story becomes one of healing, loyalty, and learning that love—not appearances—defines family.
