Rig 45

After a body is washed ashore, Petra cuts a deal to return to the rig with the police.

With Petra at large, fear spreads on board - especially since contact has been lost with the ship that they arrived on. Emma faces a Benthos crew unwilling to help with the search.

The lights go out. When the crew get them working again, a body is found.

After another murder, this time inside the sealed-off area, Emma becomes frustrated no one will talk to her.

With only hours to go before the rig explodes, an escape plan is desperately needed.

The crew realizes the killer managed to escape the rig. Help is on the way, but will it arrive in time?
