A mysterious disease has an American city in its grip, killing people with alarming speed in this pulse-pounding, action-thriller. Men In Trees co-stars Anne Heche (Hung) and James Tupper (Samantha Who?) reignite their chemistry as two strangers brought together in their urgent mission to find a cure. Heche is Dr. Tess Martin, a top virologist driven by her tragic past. Her only hope is Jack Bowen (Tupper), a rule-breaking renegade who holds the key to the disease's horrendous origins.
