A group of mysterious strangers hide near an anomaly in a theatre. Ethan and Emily have bought gravely Charlotte to the 21st century to look for medicine. But he’s too late, and Charlotte dies. Emily and Ethan are forced to flee as the ARC team investigate an anomaly. Emily escapes through the anomaly and Matt gives chase, assuming she’s about to be stranded in a different time. Matt eventually catches her when she gets knocked out by an attack from an arboreal dinosaur. With no clue as to Emily’s identity, Matt takes her to hospital. The ARC team lock the anomaly, but what they don’t realise is that two arboreal dinosaurs have come through and are still loose and in the present.

Back at the ARC, Connor has impressed Philip with his scientific know-how. Connor is obviously star struck by Philip’s charisma.

Emily escapes from hospital and Matt learns the truth about her – she’s not from this place or time. They realise a creature is loose and Emily agrees to help on condition Matt will let her back through the anomaly. Matt agrees. Whilst they track the creature through the high rise buildings of the city, Abby and Becker discover another creature is still at large in the theatre. They go head to head with their beast in the theatre’s foyer and eventually trap him and put him back through the anomaly.

Meanwhile, Emily and Matt are forced to confront the creature on the roof of the tallest building in the city. As they attempt to capture it, Matt is cornered by the creature, leaving Emily to save his life.

With both creatures taken care of and the anomaly closed, Matt realises he can’t take Emily back to the ARC – they’ll only start asking questions. After enlisting the help of a reluctant Abby, he promises her he’ll help her get back when the next anomaly opens. Until then she’ll stay secretly at his flat. Little do they know they’re being watched from the shadows by Ethan, now intent on revenge; he blames Emily for the death of his beloved Charlotte.
