Corporal Callahan Crowes returns home from Afghanistan missing part of a leg and haunted by guilt over the loss of his men. He pledges to live every moment of his life to the fullest and works to build a career in the only field he knows besides being a soldier: construction. Reeling from her fiancé's infidelity and their broken engagement, Kathleen O'Connor accepts a job far away from Boston and the suffocating pity of friends and family. She puts romance firmly behind her, and, armed with her shiny new architectural degree, launches her career with a commercial construction and design firm. Her first day on the job, she sees Cal risk his life to rescue a fellow worker, and is shocked when his act of heroism triggers an unwarranted attack on him from her supervisor. When she learns Cal may lose his job because of his leg, Kathleen urges him to use social media to fight the decision, putting her own job at risk. The public firestorm pushes Cal into the limelight in ways he least expects, but shows him a missing limb's not the barrier to love he's believed it is. But there's something besides business politics brewing at work, and when Kathleen's life is threatened, she discovers there's more to a man than two good legs-it's the size of his heart that counts.
