Molly Brown always faces life with a smile, even when a frightening thug is intent upon killing her. At first, Detective Sean Cushing finds Molly's cheery disposition unnatural, especially when he discovers the seriousness of her injuries. When she asks for police protection, he instead offers her a job and home being a nanny to his five-year-old daughter, hoping her cheery disposition can pull his child from her dark hole of misery. Never did he expect he'd be proposing marriage within a day, but life has a way of going in odd directions when Molly Brown is involved.
