After her mother's death, 13-year-old Becky goes on a weekend getaway with her father, Jeff, to bond and reconnect with him. Jeff, however, has a different plan—he brings along his new girlfriend Kayla in an attempt to bring her closer to Becky. However, when four newly-escaped prisoners show up and break into the lake house they are staying at, their plans change, and the fun trip becomes a nightmare. Becky now has to do everything she can to keep the three of them safe.
