Unimatrix Zero (I)

An enclave of Borg drones devise a dreamscape that gives them a world unfettered by their tecnological, mass-mind utilitarian society. Individual Borg enter this matrix during their regeneration cycles. When Janeway learns of the development, she identifies it as a possible means to foster Borg insurrection, and works with Seven of Nine to plant a virus in the program. But Seven of Nine gets distracted - first by an attractive male Borg she encounters in the dreamscape, then by the discovery that she may be able to rescue her father.
