Two little boys are missing, and a ransom note has arrived. The FBI sends a team of experts, but Jennifer has another idea. Why not enlist the services of Elvis, the biggest and best tracking dog in the county? The lovable Saint Bernard (who fancies himself a bloodhound) may be a bit past his prime, but he and Jennifer embark on an unforgettable adventure that turns out to be the boys' only hope for survival. And as the situation becomes increasingly dangerous, Jennifer's own life may depend on the courage of her canine partner.
