Chelsea Higgins is doing just fine. She´s heading into the holidays at the helm of a thriving dog training business, and she´s got a mellow senior dog at home to keep her warm at the end of the day. What more could she need? Enter certified gym bro Andrew Gibson: Chelsea´s former nemesis, and now the newest neighbour in her business complex, who also wants to expand into the vacant space Chelsea´s been eyeing for months. Who cares if it´s the season of joy? Let the turf war begin. When an unfortunate (and literal) run-in with Andrew´s lawless dog leaves Chelsea with a bum wrist, the two strike a deal; Andrew will help Chelsea rehab the injury if she´ll help him get through to the wild man at the other end of the leash. Their typical bickering soon turns to bantering, and Chelsea finds herself inexplicably drawn to the man she thought she had nothing in common with. As she gets to know Andrew and his parents, she realizes she needs to refocus on her own family, especially with a milestone Christmas speeding toward them. But Chelsea can´t help wondering if she and Andrew are training for keeps, or if this unexpected Christmas gift is just too good to be true.
