Fishtank is a fully monitored smart house, live 24/7. Eight contestants compete over 42 days to become the last fish standing and bring home the grand prize.

In the winter of 1972, ten contestants enter the Fishtank. Under constant surveillance, the ten "fish" will have no outside contact, except for messages sent live from viewers at home. By remaining in the tank and staying ahead of their opponents in challenges, one winner will walk away with a 50k grand prize. What's gonna happen next in this here Fishtank? Well, you never know!
