The Lilac Bloomsday Race brings worldwide competitors to Spokane to run in one of the largest, annual, timed road races in the nation. Despite his better instincts, solitary Detective Rex Begonia gets recruited for the Spokane Police Department's corporate cup running team. That's just the beginning of the teamwork as Rex and his partner Ivy Lizei join forces with wildlife officers, tribal police, Border Patrol officers and more to solve a murder and an international smuggling operation. Rex finds himself caught up in a double Bloomsday -- one in which he participates in the Lilac Bloomsday Race and a second in which he is in a race for his life.
