Samurai Cowboy (1994)

When his best friend dies of an heart attack due to permanent stress at work, the Japanese businessman Yutaka Soto quits and fulfills himself a dream: he buys a ranch in Montana to live on. However the ranch turns out to be due for demolition and the welcome by the people is less than friendly: Hotel owner Cord Wingate wanted the ranch himself and now sabotages Yutaka. Only veterinarian Jessy and an old Cowboy help him. -- Tom Zoerner
