meets up with his classmate Lisa Baiocchi. Just like Bobby, Lisa attends therapy sessions with Matthews as her father Eugene is abusive, Bobby tells Lisa that she should not take any more abuse from Eugene. When Lisa returns home her father angrily tells her to stop seeing Bobby. Suddenly a mysterious arm-like appendage bursts through the window and yanks him outside. The next day Scully examines the body and concludes that he was pushed out of the window. Mulder however, thinks he was pulled. While examining Eugene's corpse Mulder finds a splinter in his neck, the wood of which matches the trees outside his house. While they continue to investigate the crime Mulder and Scully are approached by a mysterious man (George Josef) who claims that a "bad man" is killing the area's trees. While this is happening, Matthews takes Lisa to her house claiming that she is protecting her. After Lisa overhears Matthews arguing with a man she journeys into Matthews' root cellar where she finds a corpse. When she tries to leave she finds she has been locked in. Mulder later discovers that Matthews' father was retrieved from a mud puddle twenty years before the events of the episode. He begins to suspect her of wrongdoing suspicion that is furthered after he digs up her father's empty coffin. Later the mysterious man from earlier tells Mulder that Matthews' father's death ended a blight that had been killing trees in the town. Lisa's aunt journeys to Matthews' house to retrieve her niece, but is killed by Matthews who is revealed to have a split personality engendered by abuse from her own father. This has also given her power to control the trees in the area. Mulder and Scully later search Matthews' house and find the mysterious corpse in the basement who they realize is the body of Matthews's father as well as an unharmed Lisa. Meanwhile, Matthews goes to Bobby's house and chases him into the orchard. The agents show up soon thereafter and both Mulder and Bobby are nearly drowned in mud. The mysterious man suddenly appears and cuts Matthews' head off with an axe, ending her power over the trees.
