Meanwhile, Monet attracts the attention of multiple entertainment agencies after a stunning audition, including La Hui. However, a rumor surfaces online that could potentially destroy everything she has worked for.

After encountering peril and beating death, the seven people who managed to escape the island alive struggle to stay out of facing trouble with the law. However, all seven of them find a threatening message in their rooms that shocks them. Meanwhile, Matthew Lee appears just in the nick of time to help the seven survivors with the police investigation.

Meanwhile, Monet's guilty conscience haunts her while her relationship with La Hui deteriorates. Later, Matthew gathers the seven survivors and watches them struggle and blame each other for their survival.

After another death to cover up the incident on the island occurs, Matthew determines to use the Seven to find the mastermind behind it all.
