Krista and Tatiana Hogan are two year-old conjoined twins from Vancouver, Canada. They spend every waking moment together. They share the same renal system, the same blood vessels and the same brain. But can conjoined twins share the same thoughts? Krista and Tatiana’s unusual physiology has confounded doctors and specialists alike. Fused at the frontal lobe and sharing key blood vessels, the girls’ bodies are inextricably linked. But recent findings proved that the Hogan’s unique and mysterious bond goes way beyond skin and bone. Thanks to advancements in brain scanning technologies, recent scans revealed the girls share more than a third of their brain. But what the scans also revealed was to astonish doctors, bringing into question the very nature of individuality and the self. They respond to stimuli in unusual ways; if Krista has a dummy placed in her mouth, Tatiana will stop crying. If you tickle Krista, Tatiana will start laughing. Their mother, Felicia, now believes that they are capable of seeing through each others’ eyes and tuning in and out from one another. So just how closely are they connected emotionally as well as physically - and what will this mean for their development as individuals? This observational documentary will follow the twins as they start to become conscious of one another and learn to co-exist for the first time. With exclusive access to the incredibly brave and loving Hogan family as well as Dr. Cochrane and his team of specialists at British Colombia Children’s Hospital, this extraordinary film will record the girls’ first words and first steps, following them over a year as the family learns to cope with raising conjoined toddlers.
