Ever since their opening in 2015, Popcorn Ent. has been rounding up male trainees in the hopes of debuting the next hit for the K-POP industry. Some they even had to drag down from larger companies. Now they have 12 impatient boys who wish to fulfill their dreams as superstars in their below level practice rooms anxiously practicing and praying for their climb to fame to begin. Their friendships grew and their teamwork excelled as they took each other hand in hand and all prepared for their future as an idol group.

However, Popcorn's CEO, Jang Heojin, refuses to debut a boy-group, especially their first act, of more than 6 members. Popcorn has to cut off half of them to suit the needs of the CEO. Dreams and lives are at stake, the once friends must battle for a place in the boy group, and some are willing to go straight to the edge for it. They will acheive their Deadly Dreams of being a singer even if it means leaving a brother behind or fall behind and be dropped.
