Just One Look: Who kidnapped Jacek, and what is his real identity?

As Greta starts to unravel the mysteries related to the photo, the first thing that surprises her is her husband’s real identity.
As the photo suggests, all of the mysteries surrounding the current investigations are linked to a concert in 2009 that all of these individuals, including Greta, attended.
It is revealed that Jacek, Alex, the girl in the photograph, and Szymon were part of a band, LAAD, and Jacek was involved in a fight with the singer in the concert, Jimmy, as he accused him of stealing his song, Just One Look. During the fight, Jacek is hit by a sharp object and dies instantly. To let the royalties come to her, Jacek’s sister, Sandra, asks Szymon to pretend to be Jacek, and he has been carrying the act for 15 years.
However, after encountering the photograph, Szymon wants to come clean to his wife Greta but is kidnapped and beaten by Sandra’s men as she doesn’t like the secret being unraveled.
Just One Look: Sandra was the mastermind behind everything

Ultimately, it is revealed that Jacek’s sister, Sandra, who initially posed as a lawyer, is the real mastermind. After Jacek is killed in the fight, which Sandra instigated to claim the royalties of the song, she orchestrated the arson that took place in the concert and killed many people in the stampede.
She is also the one who kidnapped Szymon when he wanted to tell the truth to his wife, Greta. Her men beat him up badly, which results in him dying due to a cardiac arrest in the hospital.
Sandra is later found to be guilty of all the crimes she committed to claim her brother’s money and is arrested.
Other revelations in Just One Look

Alex’s father, prosecutor Borys Gajewicz, reveals at the end that he was the one who planted the photograph in Greta’s envelope as he wanted to find out who murdered his daughter.
He initially contacted Greta and told her that he received the same photograph and knew that his daughter was murdered. His intuitions are confirmed when a hit-man named Marek calls him and confesses to killing Alex.
After all the mysteries are solved and Greta’s suppressed traumatic memories come to the fore, she remembers the last important detail about the events that unfolded: that she took the photograph of Jacek, Alex, Szymon, and the others.
